First, we need to find the area of the wall.  We do this by multiplying the length times the width.  This is equal to 42*25.5=1070 square feet.  Now, we divide the cost by the area to find our answer.  This is equal to 

771.12/1070=$0.72 dollars per square foot, or answer B.

What is the slope of 4x+5y= -10
Aleonysh [2.5K]

Answer:

-\frac{4}{5}

Step-by-step explanation:

To find the slope, rearrange the equation to y=mx+b or y=mx+c.

4x+5y=-10

Subtract 4x from both sides:

5y=-10-4x

Divide 5 on both sides:

y=\frac{-10-4x}{5}

y=-\frac{4}{5} x-2

In the equation of y=mx+b/y=mx+c, m will be the slope.

Therefore, the slope is -\frac{4}{5}

Slope= 5 and passes through (-2,0) in slope-intercept form
lilavasa [31]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m = 5 → y=5x+b

and point (-2, 0). Substitute:

0=-2(5)+b

0=-10+b       <em>add 10 to both sides</em>

10=b\to b=10

<h3>Answer: y = 5x + 10</h3>
