28) Using the standard form of linear equation: y-0=-3(x-8)=3x-24, the equation is y=3x-24

36) Slope m=(8-8)/(-3-4)=0. Using the standard form of linear equation: y-8=0(x-4)=0, the equation is y=8

40) Transfer 2y+x=7 to standard form to get y=-x/2+7/2. Hence the slope m=-1/2. Since our target line is parallel to y=-x/2+7/2, the slope of our target line is m=-1/2. Since the target line passes through (-5,-4), using the standard form of linear equation: ...
