Question

The slope of a line is 8 and the point (-6, -16) is on the line. Express the line in slope-intercept form.


Select the best answer from the choices provided.



y = -16x + -104



y = 8x + 32



y = 8x + 122



y = -16x + 32

Answer 1

slope intercept form : y = mx + b .... m is your slope and b is your y intercept

y = mx + b
slope(m) = 8
(-6,-16)....x = -6 and y = -16
we already know slope(m) is 8, so now we need to find the y intercept (b)
now we sub
-16 = 8(-6) + b
-16 = -48 + b
-16 + 48 = b
32 = b

so your equation is : y = 8x + 32
