Answer:
y = 2x - 1 Graph B
y = 2x + 2 Graph A
y = 2x - 5 Graph C
Step-by-step explanation:
y = mx + c
c is where the line intersect the Y axis.
<h2>Substitute x for 0:</h2>
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.
