Answer :
Given point (2,8) and slope, we can use slope intercept form.
y-y1=m(x-x1)
y-8=-2(x-2)
y-8=-2x+4
y=-2x+12
Where, y=mx+b, b is the y intercept.
In this case, the intercept is 12.
y-y1=m(x-x1)
y-8=-2(x-2)
y-8=-2x+4
y=-2x+12
Where, y=mx+b, b is the y intercept.
In this case, the intercept is 12.
