How do you find the slope for 2x+y=7?

Answer 1

Avery Alexander

It is #-2#.

The slope is the number multiplying the #x# when the equation is in the form

#y=mx+q#

then we convert the equation to that representation.

#2x+y=7#

#y=-2x+7#

and the slope is #-2#.

To find the slope for the equation (2x+y=7), you first need to rewrite the equation in slope-intercept form, which is (y = mx + b), where (m) represents the slope. So, you would solve the equation for (y) to isolate it on one side of the equation. Then, the coefficient of (x) will be the slope. In this case, rearranging the equation (2x+y=7) to solve for (y), you get (y = -2x + 7). Therefore, the slope (m) is -2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
