This table gives a few (z, y) pairs of a line in the coordinate plane.
-56 66
-42 58
-28 50
what is the y-intercept of the line?

The y-intercept of the line is 34.

Step-by-step explanation:

There are few points on the z-y plane through which a straight line passes.

The points are (-56,66), (-42,58) and (-28,50).

Now, take the first two points to get the equation of the straight line.

The equation is

⇒

⇒ 14(y - 58) = - 8(z + 42)

⇒

⇒

This equation is in slope-intercept form.

Hence, the y-intercept of the line is 34. (Answer)
