14x = 7y+28 -7y = -14x+28 Divide all terms by -7 to find the value of y: y = 2x-4 which is now in slope intercept form
If: -14x = -98 Then: x = 7
Standard form is y = mx + b where m = slope 2y = -14x + 22 divide both sides by 2 y = = -7x + 11 slope = m = -7
14x+7y=-9
are those two different problems ? ... i am going to solve them as if they are 14x-2y=78 (re arange the terms to be easily solved) -2y=78-14x (times by -1) 2y= -78+14x (divide all terms by 2) y=-39+7x (so) y=7x-39 2x-2y=6 (re arange the terms to be easily solved) -2y=6-2x (times by -1) 2y=2x-6 (divide all terms by 2) y=x-6
