Question

The points (-16,r) and (-4,11)lie on a line with slope 1/2. Find the missing coordinate r?

Answer 1

Answer: The missing coordinate R is 5.

Explanation:

11=1/2(-4) + B

11=-2 +B

B= 13

B represents the y-intercept

so we will use the equation y=mx + B and we know the slope and y intercept.

r= 1/2(-16) + 13

r= 5
