Since the slope of your original line is -1/2 the slope of the new line is 2. Then to determine the y intercept of the new line you will use the point which the line passes through (1,-6) and the slope, which was 2. Plug 1 in for x, -6 in for y and 2 in for m in y=mx+b. B with then be equal to -4. Therefore the equation for the new line will be y=2x-4. Then put this equation back into standard form by getting both the x and y terms on the same side of the equation, it will then look like, 2x-y=4.  |
He said you may wanna double check to see if he screwed up. LOL
