Question

Write an equation in point-slop form of the line through joint J(4, 1) with slope -4.

please help ?? :))

Answer 1

y - y1 = m(x - x1)

Where my is the slope and y1 and x1 are your points.

Answer 2

ooo, okay i get it now. haha, thank you so much !!

Answer 3

No problem. Remember

The forms of:

STANDARD
Ax + Bx = C

POINT-SLOPE
y - y1 = m(x - x1)

SLOPE INTERCEPT FORM
Y = mx + b

If you are EVER given something like a slope and points, and asked to graph it, first put it in POINT SLOPE FORM then solve for y, that will give you y = mx + b, and you can graph it then.
