Best ResponseYou've already chosen the best response.0just 2 actually. :) and parallel lines have the same slope so the slope of the parallel line is also 2. You can write the equation in point slope form \[yy_1=m(xx_1)\] m is the slope, so that's 2 (x_1,y_1) is the point so that's (2, 1)

Best ResponseYou've already chosen the best response.0y + 1 = 2(x  2) y + 1 = 2x  4 y = 2x  5 2x  y = 5

Best ResponseYou've already chosen the best response.0y = 2x – 5 can it be written like this

Best ResponseYou've already chosen the best response.0yes that's slope intercept form. y + 1 = 2(x  2) is point slope form 2x  y = 5 is standard form 3 different ways to write the same equation
