Inessa05 [86]

Answer:

Policeman A = 56 tickets

Step-by-step explanation:

Find the slope of the line (-3,-3) (1,1)
Volgvan

Answer: The slope is m = 1

Step-by-step explanation:

-To find the slope, you need the slope formula:

m=\frac{y2-y1}{x2-x1}  where you have (x1,y1) and (x2,y2) on the equation.

-Next, you put the two points to the equation:

m=\frac{1+3}{1+3}

-And then you solve the equation:

m=\frac{1+3}{1+3}

m=\frac{1+3}{1+3}  = \frac{4}{4}=1

m=1
