Answer 2

Replace x with 0 and solve for y


2y+6 = 5x
2y+6 = 5*0
2y+6 = 0
2y+6-6 = 0-6 ... Subtract 6 from both sides.
2y+0 = -6
2y = -6
2y/2 = -6/2 ... Divide both sides by 2 to isolate y.
1y/1 = -3
1y = -3
y = -3


So the y-intercept is -3. What does this mean? It means that the graph crosses the y axis at the point (0,-3)
