Best ResponseYou've already chosen the best response.1pointslope form: y  y1 = m(xx1) plug in slope (1/2) for m, 2 for x1, and 4 for y1, then rearrange and solve

Best ResponseYou've already chosen the best response.0I plugged in the numbers and got y(4) = 1/2(x2). Explaining it now I realize I don't even know how I got my answer. I think I rearranged wrong and miscalculated somewhere

Best ResponseYou've already chosen the best response.1yes, your plugging in is right but you may have made a mistake in the rearranging y(4) = 1/2(x2) y+ 4 = 1/2(x)  1 y = (1/2)x  5

Best ResponseYou've already chosen the best response.0Why did 4 become positive and where did the 1 come from? @vocaloid

Best ResponseYou've already chosen the best response.14 becomes positive because y(4) = y + 4 (remember that two negative signs together become positive) 1/2(x2) = 1/2(x)  1 because you distribute the 1/2 1/2(x2) = (1/2)(x)  (1/2)(2) = (1/2)x  1
