Question

A line that includes the points (

–
4,f) and (
–
3,5) has a slope of 7. What is the value of f?

Answer 1

Answer: f = 12

Explanation:

Answer 2

Answer: f=12

Explanation:

Slope is rise/run

slope=7

rise/run=7

rise= y2-y1

run=x2-x1

slope=5-f/3-4

slope=5-f/-1

7=5-f/-1

multiply both sides by -1

-7=5-f

subtract 5 from both sides

-12=-f

divide both sides by -1

f=12
