What is the slope of the line through (1, -1)and (5,-7)
Choose 1

-3/2

Step-by-step explanation:

the formula for slope is y1-y2/x1-x2

where

y1 is the first point's y coordinate

x1 is the first point's x coordinate

y2 is the second point's y coordinate

x2 is the second point's y coordinate

so now we can plug our points in

-1-(-7)/1-5

6/-4

simplify

-3/2

Step-by-step explanation:

Subtract the "Y" values from the ordered pairs   -1 - (-7)= 6

Subtract the "X" values from the ordered pairs   1-5 = -4

Remember slope is rise over run or y over x so the answer is -6/4 or -3/2 reduced

I always bring my negative to the top after I finish solving

Since you didn't provide the choices your answer is either going to be 3/-2  or -3/2 depending if your teacher makes you bring the negative to the top

70

step-by-step explanation:

2*5=10

4*15=60

60+10=
