Slope is 1 and (-2,-1) is on the line

y = x + 1

Step-by-step explanation:

Since slope is 1, then the equation will be formatted as y = x+b, since m is 1. Now we need to solve for b, since we're given a coordinate that is on the line, replace x and y for these two points to solve for b.

y = x + b (subsitute)

-1 = -2 + b (add 2 to both sides)

1 = b

So your final equation is y = x + 1.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
