use point slope form.. \[y  y_{1} = m(x  x_{1})\]

Slopeintercept form is y = mx + b All you do is plug in the slope and the point given in the problem and then figure out the yintercept. (b) m is the slope and x and y is the point given. (4, 2) (x, y) So plug these into the formula and solve for b. Once you find b, then you plug it back into the formula along with the slope and you're done.

Yes, but put in the slope as m. Then you can solve for b.

Slope Intercept form: y = mx + b y axis = 2 so *2 = mx + b* x axis is 4 so * 2 = m(4) + b m = slope sp *2 = 1/2(4) + b now multiply 1/2 * 4 to get 2 now we have 2 = 2 + b subtract 2 from each side b = 0

1/2 is the slope. Plug it in for m.

1. 2 = 1/2(4) + b 2. 2 = 2 + b 3. subtract 2 from each side to get b = 0

Thanks for just giving her the answer, Storm. She was about to do it on her own.

the thing isthats nit one of the answers y = 1/2 x + 2 y = 1/2 x y = 1/2 x + 4

Since b is 0, you just don't need to have it there.

So you plug the slope back into the original equation once your have b. But in this case, you just plug the slope into the equation and ignore b.

y2=1/2(x4) y2=1/2x2 add 2 on both sides y=1/2x here y intercept is 0
