Question

What is the answer?please help me

Answer 1

y = 2x - 1 Graph B

y = 2x + 2 Graph A

y = 2x - 5 Graph C

Explanation:

y = mx + c

c is where the line intersect the Y axis.

Substitute x for 0:

y = 2x - 1

2 * 0 - 1 = -1.

This is graph B because it intersects at 0,-1.

y = 2x + 2

2 * 0 + 2 = 2

This is graph A because it intersects at 0,2.

y = 2x - 5

2 * 0 - 5 = -5

This is graph C because it intersects at 0,-5.
