Question

When graphing the equation y = - 3/4x + 2, Sally

started by graphing the point (2,0). Then, she used
the slope to find the next point. She started at the
point (2,0) and counted down 3 units and to the right
4 units. What was Sally's mistake?

Answer 1

Sally started by graphing the point (2,0) is wrong

Explanation:

We know

The equation is y = - 3/4x + 2

M = -3/4

Y-intercept located at (0, 2)

Sally started by graphing the point (2,0)

This is wrong because (2,0) is the x-intercept, not the y-intercept!

So, she is wrong right at the beginning.
