What is the slope of the line by the equations below? y-9=15 (x-5)

To find the slope, you should rearrange the equation into slope-intercept form, ie. y = mx + c, where m is the gradient.

y - 9 = 15 (x - 5)

y = 15 (x - 5) + 9 (Add 9 to each side)

y = 15x - 15*5 + 9 (Expand 15 (x - 5))

y = 15x - 75 + 9

y = 15x - 66

Therefor, the slope of the equation is 15.

Use the slope-intercept form

y

=

m

x

+

b

to find the slope

m

.

m

=

15
