Question 164976: I am having a hard time wrapping my brain around Slope and Intercepts. Can you help answer the question below?
What is the slope and y-intercept of the following equation: 7x + y -28 = 0?
Thanks,

Found 2 solutions by Mathtut, Edwin McCravy:Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website! some things in math can be that way. when your searching for slope and intercept there is a format you must rewrite the equation to match. The format is y=mx+b where m is the slope and b is the y intercept. re writing our equation we subtract 7x and add 28 to both sides. everything on the left cancels out except y and now we have -7x+28 on the right so y=-7x+28 an this is in the right format slope is the number that is multiplied by x so m=-7
and the y intercept is b=28
slope = -7
y-intercept = 28 Answer by Edwin McCravy(20056) (Show Source): You can put this solution on YOUR website! EDWIN'S SOLUTION:
Change it to the slope-intercept form
Solve for
So when you compare that with
You can see that the slope, m, is -7, the coefficient of x,
and the y-intercept is the point (0,-7).
