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}.

20 Points! Which ordered pair is the best estimate for the solution of the system of equations?
yan [13]

Answer:

The best estimate for the solution is the ordered pair  (-6.5,-3.5)

Step-by-step explanation:

we have

y=\frac{3}{2}x+6 ------> equation A

y=\frac{1}{4}x-2 ------> equation B

we know that

using a graphing tool, the solution of the system of equations is the intersection point both graphs

The intersection point is (-6.4,-3.6)

therefore

The best estimate for the solution is the ordered pair  (-6.5,-3.5)
