2. The line y = 4x - 7 crosses the y axis at:

a.(4, 0)
b.(0, 4)
c.(-7, 0)
d.(0, -7)

Set y=0 and solve for x
You can automaticallly elimintae b. and d. because y has to be 0 when the line crosses the y-axis. Something seems to be wrong with your other choices too, recheck them. Are you sure you have the right equation for the line too?

To find where the line y = 4x - 7 crosses the y-axis, we need to find the point where the line intersects the y-axis, which is the point where x = 0.

Substituting x = 0 into the equation y = 4x - 7, we have:
y = 4(0) - 7
y = 0 - 7
y = -7

Therefore, the line y = 4x - 7 crosses the y-axis at the point (0, -7). Therefore, the correct answer is:

d. (0, -7)
