Question

Need help with line slope formula

Answer 1

Hi!

Explanation:

Lesson: Slope/ and slope-intercept form

`SLOPE=(Y^2-Y^1)/(X^2-X^1)=(RISE)/(RUN)`

`((-5)-9=-14)/(4-(-3)=4+3=7)=(-14)/(7)=-2`

Therefore, the slope is -2.

Answer is -2.

I hope this helps you!

Have a nice day! :)

Answer 2

To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2). The equation used to calculate the slopefrom two points is: On a graph, this can be represented as: There are three steps incalculating the slope of a straight line when you are not given its equation.
