-19

Answer 1

to find f(-3) , just put x=-3 in f(x)

Answer 2

Answer 4

Good point.

Answer 5

-2/3

-3/2

Answer 6

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 7

So?

Answer 8

so put the values of x1,y1,x2,y2 and get m using that formula.
