Which of the following is the correct equation and graph of the line with slope –2 and y-intercept (0, 0)?

Question

a.y = x – 2
b.y = –2x
c.y = –2x
d.y = x – 2

Explain how you would get this as well.

Answer 1

y=mx+b m is the slope

(0,0) works for y=-2x

so it is either b or c (they are the same)
