Question

Question 1 (1 point) What is the difference between the two y-intercepts? Function A Function B X X у у 7 1 2 11 3 11 3 16 5 15 4 21

Answer 1

step 1

Find the equation of function A

Find the slope

take the points

(1,7) and (3,11)

m=(11-7)/(3-1)

m=4/2

m=2

Find the equation in point slope form

y-y1=m(x-x1)

we have

m=2

(x1,y1)=(1,7)

substitute

y-7=2(x-1)

Find the y-intercept

REmember that te form

y-y1=m(x-x
