Question

Find the slope of the line that passes through the points (5,8) and (9,20)

Answer 1

Answer:

Slope = 3

Step-by-step explanation:

the points (5,8) and (9,20)

A point is always written in the form (x, y)

(5,8) and (9,20) is in the form (x1, y1)  and (x2, y2)

Slope =( y2 - y1) / (x2 - x1)

x1=5, x2=9,y1= 8, y2 = 20

Slope = (20 - 8) / (9 - 5)

Slope = 12/4

Slope = 3

Equation to find slope with two points:

y2-y1
——— = m(slope)
x2-x1

Answer:
m = 3
