Question

Find the slope of the line that goes through the points (0,-15) and (11,-4). Slope: m = __

fill in the blank

Answer 1

Suppose that :

A = ( 0 , - 15 )

&

B = ( 11 , - 4 )

Slope = m = [ y(A) - y(B) ] ÷ [ x(A) - x(B) ]

Now let's juts put the coordinates in the formula to find the slope :

Slope = m = [ - 15 - ( - 4 ) ] ÷ [ 0 - 11 ]

Slope = m = [ - 15 + 4 ] ÷ [ - 11 ]

Slope = m = - 11 ÷ ( - 11 )

Slope = m = 1
