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