A line intersects the y-axis of the point (a, b) Is a = 0? Is b = 0? Explain.

9514 1404 393

  a=0

  b may be 0 but is not required to be

Step-by-step explanation:

The y-axis corresponds to the line x=0. Any point on the y-axis will have an x-coordinate of 0.

If (a, b) is on the y-axis, then a = 0.

If the intersection point is (0, 0), then b=0. Otherwise, b is not 0.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
