Question

A line passes through the points (4, 19) and (9, 24). Write a linear function in the form y=mx+b for this line

Answer 1

Answer:

y=x+15

Step-by-step explanation:

1. find the slope

m=(24-19)/(9-4)

m=5/5

m=1

2. plug slope into slope intercept formula

y=1x+b

y=x+b

3. plug in for x and y from either coordinate point (just make sure they are from the same point!!)

24=9+b

15=b

4. plug m and b into formula

y=x+15
