Question

How do i figure out from a already graphed graph what the equation​

Answer 1

Put the equation in slope intercept form first. it’ll look somewhat like
y=mx+b (m is your slope and b is your y-intercept). you find your slope by drawing slope triangles. to draw a slope triangle, find two points and draw a triangle to connect them together. then you see how many it goes up/down and how many it goes to the side, left/right. the y-intercept is where the point crosses the y axis when x is 0.
