Question

Find the slope of the line passing through the points (-5, 3) and (7,9).

Answer 1

`\huge\boxed{slope=(1)/(2)=0.5}`

Explanation:

The formula of a slope:

`m=(y_2-y_1)/(x_2-x_1)`

We have the points

`(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9`

Substitute:

`m=(9-3)/(7-(-5))=(6)/(7+5)=(6)/(12)=(6:6)/(12:6)=(1)/(2)`

Answer 2

1/2

Explanation:

We can use the slope formula since we have 2 points

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

= (9-3)/( 7 - -5)

= (9-3) /( 7+5)

= 6/ 12

= 1/2
