Answer 14 or 15, or both if you want. you for the !

14.

we look for where the graphs of f(x) and g(x) intersect; we see they do at (-2,4) and (1,1).

the solutions will just be the x coordinate, x=-2 or x=1

15.

what information do we need? if we know it's a line we just need two points on it.

the variable m represents the slope of the line and b is the y intercept.

the y intercept is the value when x=0, so b=-1

the slope is the change in y divided by the change in x, so we can just pick the first two points.

m = (-1 - -7)/(0 - -2) = 3

y = 3x - 1

it checks for the other points.
