Question

Use the ordered pairs to write a function rule. Give the rule in the slope-intercept form.

(–12, 1.5), (−1, –1.25), (5, –2.75), (8, −3.5)

Answer 1

apply the slope formula

m = (y2-y1) / (x2-x1)
where your (x1,y1) and (x2,y2) values come from any two points in the list

from there, you can use

y = mx + b
plug in m, plus any x,y, coordinate from the list, and solve for b
