What is the slope of the line through (-1,-7), (3,9)

Sagot :

Answer:

The slope is 4

Step-by-step explanation:

basilly you add easy x(-1,-7) + y(3,9) = 2/2

make sure that you add x left and y right  first -1+3=2 and then -7+9=2 equal=2,2 together and just add both equal 4

Most easy just put you answer in a graht and count the squares

hope this helps ;)

Equation for slope = (y2-y1)/(x2-x1)

= (9- -7)/(3- -1) = 16/4 = 4
