(-8,6); slope = 1/4

Turn into y intercept equation !

If you only have a point and slop you would use the formula- y-y1 = m(x-x1)

with your number the equation would be y-6 = 1/4(x+8)

the eight became a positive because in the equation the x is negative and a negative times a negative is a positive*

you would the solve the equation to be in y=mx+b form and it would be
y=1/4x +8

i hope this helped
