# Is this right? A line has a slope of -4 and passes thru the point (2, 3). Then an equation for that line is...

y = 3x - 10

Can't be

in the form "y = mx + b"

the slope is "m"

y = -4x + b

3 = -4*2 + b

11 = b

You need to use the point-slope equation; (y - y1) = m(x - x1).

Substitute -4 for m, 3 for y1 and 2 for x1.

That gives;

y - 3 = -4(x - 2)

y - 3 = -4x + 8

y = -4x + 11

the standard slope form is y=mx+b, where m is the slope. in this case its -4....input your values into the equation and you get

3 = (-4*2) + b

3 = -8 + b

11 = b

so the equation would be y=-4x+11
