  • How can I explain slope-intercept form to a student who keeps . . . - Wyzant
    I help students understand slope-intercept form by connecting the abstract symbols to real-world, visual examples I explain that “m” is the slope, or how steep a line is — like the rise over run on a hill, while “b” is the y-intercept, the point where the line crosses the y-axis, like the starting point of a race or a bank account
  • How do you tell if the slope is positive or negative? - Wyzant
    Algebra 1 Prealgebra Asked • 07 30 24 How do you tell if the slope is positive or negative? I know that there are four different kinds of slope, but I get really confused between positive and negative slope There's undefined slope, positive slope, negative slope, and undefined slope
  • Rectangle TUVW is on a coordinate plane at T (a, b), U (a + 2, b + 2 . . .
    Because the slope of the line doesn't depend on the constants a and b, you can plug in values for a and b The easiest way of doing this is just making both a and b equal to 0 Therefore we get points T (0,0), U (2,2), V (5,-1), and W (3, -3) Get the slope of line segment UV: Use the formula: m = (y 2 - y 1) (x 2 - x 1) Any line parallel to this line segment will have the same slope
  • Line g is shown on the graph. coordinate plane with line g . . . - Wyzant
    The slope is therefore 3 3, which is equal to 1 Second, solve for b Slope intercept form is y = mx + b, where b is a constant and m is the slope We can use any coordinates of any point on the line g to find b, and I will use (0,5) for this example Filling in the slope intercept form with these coordinates creates the equation 5 = 1 (0) + b
  • How do I rearrange t^2 = 4pi^2 L g in y=mx format? - Wyzant
    You put T2 on horizontal axis and L - on vertical Then you need to find the slope of this graph (tan of the angle between the graph and horizontal axis) Now you can write g = 1 4π2 x Slope Hence, if now you divide the slope of the graph by 4π2  , you will get the experimental value of the acceleration due to gravity g And you are done
  • what is Graphing Linear Equation using Slope intercept form
    The linear equation being in slope-intercept form immediately gives us the y-intercept, so, e g , if we're graphing y=-2x+3, since 3 is the y-intercept, we can immediately plot (0, 3)
  • What is an equation of the line through (0, –3) with slope 2 5
    Since you know the slope and you know one point, all you have to do is plug the slope and the coordinates into the slope-intercept form and solve for b y = mx + b y=-3 x=0 and m=2 5 -3 = (2 5)0 + b Since 2 5 (0) is 0, b must be -3 So the equation is y = (2 5)x - 3 You can check your answer by finding another point on the line and verifying that the equation works for that point, as well Add
  • Slope and Linear Equations Tips | Wyzant Ask An Expert
    Slope and Linear Equations Tips Slope and Linear Equations: Finding the slope of a line given two points or an equation Writing the equation of a line given its slope and a point, or two points Graphing linear equations in slope-intercept form (y = mx + b)
  • How do I find equation of the line that satisfies the given . . . - Wyzant
    A line that is parallel to another has the same slope as that other line So, to find the slope of the line in question, we just need to find the slope of y = 5x - 1
  • How do I find slope-intercept form of a line passing through . . . - Wyzant
    the slope is -2, and the y-intercept is 5 This means the line crosses the y axis at the point (0, 5) Plot the y- intercept Start by putting a point on the graph at (0, 5) Use the slope to find another point from (0,5) move right 1 and down 2 to reach the next point, (1, 3) Connect the points with a straight line and extend in both
