Math question if you multiply my number by 4 at -4 to the product and then take one third of the sum the result is -6 find my number

the answer is c)8

step-by-step explanaction:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

=

x=0.8898305 is the answer to that equation
