Question

What is the slope of the line that
asses through these two points?
(1, -2)
(3, 4)

Answer 1

`(\stackrel{x_1}{1}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{4}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{4}-\stackrel{y1}{(-2)}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{1}}}\implies \cfrac{4+2}{2}\implies \cfrac{6}{2}\implies 3`

Answer 2

3

Explanation:

slope = y2-y1/x2-x1

from the question above,

X1= 1 Y1= -2

X2= 3 Y2= 4

SLOPE OF THE LINE

= 4--2/3-1

= 4+2/2

= 6/2= 3

slope of the line = 3
