What is the slope of the line given by the equation -3x = 30 - 5y?

zaharov [31]

Answer:

The slope of the line given by the equation -3x=30-5y is $\frac{3}{5}$ .

Step-by-step explanation:

-3x=30-5y

Move the -3x to the right side of the equal sign and the -5y to the left.

5y=30+3x

By switching them to opposite sides, their sign changes from - to +.

Then, divide both sides by 5 in order to isolate the y.

$\frac{5y}{5} = \frac{30+3x}{5}$

You get:

<em>y= </em> $\frac{3}{5} x +6$ <em />

According to y=mx+b, mx refers to the slope.

In this case, the slope would be $\frac{3}{5}$ .
