Question

11. Find the slope of a line that passes through (3,-2) and (-4,-9).

A. 1
B. 1/3
C. -2/5
D. -1
​

Answer 1

A) 1

Slope = m

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

(3, -2) and (-4, -9)
x1, y1 x2, y2

m = (-9 - (-2)) / (-4 - 3)
= (-7) / (-7)
m = 1

Remember: two negatives make a positive
