Which is the equation of the given line? (-10,-7) (3,-7)
Vladimir [108]

Answer:  y=-7

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

Find the slope with this formula:

m=\frac{y_2-y_1}{x_2-x_1}

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

m=\frac{-7-(-7)}{-10-3}\\\\m=\frac{0}{-13}\\\\m=0

Substitute the slope and any point into  y=mx+b and solve for "b":

-7=0x+b\\b=-7

Then, substituting "m" and "b" into the equation  y=mx+b, you get that the equation of this line is:

 y=0x-7

 y=-7

8. WRITE Math Explain how to determine if a given rate is also a unit rate.<br> This is hard help :c
patriot [66]
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

What is the average of 132 and 1/2 137 and 2/3
tino4ka555 [31]
If you would like to find the average of 132 1/2 and 137 2/3, you can calculate this using the following steps:

<span>132 1/2 = 265/2
137 2/3 = 413/3
</span>
132 1/2 + 137 2/3 = 265/2 + 413/3 = 795/6 + 826/6 = 1621/6
<span>1621/6 / 2 = 1621/12 = 135 1/12
</span>
The correct result would be <span>135 1/12.</span>
