Question

((-3,-10),(-1,-4),(0,-1),(2,5),(4,11)) in y=mx+b form

Answer 1

Answer:

y = 3x -1

Step-by-step explanation:

It is convenient to choose two points that have x-values 1 unit apart when computing the slope of the line (m). Here, we choose the points (-1, -4) and (0, -1).

... m = (change in y)/(change in x) = (-1-(-4))/(0-(-1)) = 3/1 = 3

The point (0, -1) tells you that the y-intercept (b) is -1.

Now you have the information you need to fill in y = mx + b:

... y = 3x -1
