To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

To graph a parabola, use the coefficient a and coefficient b values from your parabolic equation in the formula x = -b ÷ 2a to solve for x, which is the first coordinate of the vertex. Next, plug x back into your equation to solve for y, which is the second coordinate of the vertex.

To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points. Label the legs of the triangle.

Use a Graph to Solve an Equation - YouTube YouTube Start of suggested clip End of suggested clip Sign. So y equals the absolute. Value of x i'm actually going to change this one. And then minus 2MoreSign. So y equals the absolute. Value of x i'm actually going to change this one. And then minus 2 on the end this is just so we could get something that fits on our graph.
