The graph of the function f(x)=mx+b contains the points (-1,3) and (-2,4) find m and b

m = -1; b = 2

Step-by-step explanation:

the first step in solving this equation is to find the slope

so we use the equation (y2-y1)/(x2-x1)

so with this the equation is

(4 - 3)/(-2 + 1)

then it would be 1/-1

that is -1

so the function so far is f(x) = -x + b

to find the b you would plug in the coordinates

we can plug in the first set

3 = 1 + b

b = 2

so the m is -1 and the b is 2

i think it would be 42cm

answer: 12

step-by-step explanation:

because yes
