Question

Find the slope of a line containing the points (0,-6) and (-21,-18)

Answer 1

`m = 0.5714`

Explanation:

Slope Intercept Form:

• (y = mx + b)

y = 0.5714x + -6
-----------------------------------------------------------------------------------------------------------

• Start with the slope formula

`m=((y_(2)-y_(1) ) )/((x_(2)- x_(1) ))`

• Substitute point values in the formula

`m=((-18--6))/((-21-0))`

• Simplify each side of the equation

`m=((-18--6))/((-21-0)) =(-12)/(-21)`

• Solve for slope (m)

`m=0.5714`
