Question

39. write an equation in slope-intercept formof the line through point p(6, 7) with slope -2.
a)y-7=-2(x-6)
b)y=-2x+7
c)y=-2x+19
d)y-6=-2(x-7)

Answer 1

y=mx+b
plug in the point and slope
7=(-2)6+b
7=-12+b
add 12 on both sides
19=b
now that you know b plug in the slope and b
y=mx+b
soooo..
y=-2x+19

Answer 2

thanks
