How do you find the slope of 3x+y=7?

Answer 1

Slope of #3x+y=7# is #-3#

Method 1: The standard form of a linear equation is #color(white)("XXXX")##Ax+By = C#, where #-A/B# is the slope.

The second method, #3x+y=7#, can be transformed into slope intercept form as follows: #color(white)("XXXX")##y = -3x +7#. In this case, a linear equation in slope-intercept form, #color(white)("XXXX")##y = mx +b#, has a y-intercept of #b# and a slope of #m#.

To find the slope of the equation 3x + y = 7, rewrite the equation in slope-intercept form (y = mx + b), where m represents the slope. Subtract 3x from both sides: y = -3x + 7. The coefficient of x (-3) is the slope. So, the slope of the equation is -3.

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.
