Best ResponseYou've already chosen the best response.3Slopeintercept 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.

Best ResponseYou've already chosen the best response.3Yes, but put in the slope as m. Then you can solve for b.

Best ResponseYou've already chosen the best response.0Slope 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

Best ResponseYou've already chosen the best response.0ok 2=1/2(4)+b anf i try to find b right?

Best ResponseYou've already chosen the best response.01. 2 = 1/2(4) + b 2. 2 = 2 + b 3. subtract 2 from each side to get b = 0

Best ResponseYou've already chosen the best response.0the thing isthats nit one of the answers y = 1/2 x + 2 y = 1/2 x y = 1/2 x + 4

Best ResponseYou've already chosen the best response.3Since b is 0, you just don't need to have it there.

Best ResponseYou've already chosen the best response.3So 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.

Best ResponseYou've already chosen the best response.0y2=1/2(x4) y2=1/2x2 add 2 on both sides y=1/2x here y intercept is 0
