Find the slope of a line that passes through (-4,-5) and (-3,5)

10

Step-by-step explanation:

Slope m = y2 - y1 / x2 - x1

(kindly note the numerals written are subscripts)

From question;

(-4, - 5) = (x1, y1)

(-3,5) = (x2, y2)

Slope m = 5 - (-5) / (-3) - (-4)

Slope m = 5+5 / - 3 + 4

Slope m = 10 / 1

Slope m = 10
