6. Write an equation for the line that is parallel to the given line and that passes through the given point.

telo118 [61]

Answer:

The equation of new line is: $\mathbf{y=\frac{3}{4}x-12}$

Option H is correct.

Step-by-step explanation:

We need to write an equation for the line that is parallel to the given line $y=\frac{3}{4} x-9$ and point (-8,-18)

The equation of required line will in in form $y=mx+b$ where m is slope and b is y-intercept.

We need to find slope m and b y-intercept for new line.

Finding slope:

When two lines are parallel, they have the same slope.

The slope of given line can be found by comparing the equation $y=\frac{3}{4} x-9$ with $y=mx+b$

So, m = 3/4

The slope of new line will be: $m=\frac{3}{4}$

Finding y-intercept:

Using slope m = 3/4 and point (-8,-18) we can find y-intercept

$y=mx+b\\-18=\frac{3}{4}(-8)+b\\-18=-6+b\\b=-18+6\\b=-12$

So, y-intercept is b=-12

The equation of new line having m = 3/4 and b=-12 is:

$y=mx+b\\y=\frac{3}{4}x-12$

So, the equation of new line is: $\mathbf{y=\frac{3}{4}x-12}$

Option H is correct.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?

Lerok [7]

To eliminate the fraction, we multiply by 4

<h3>How to eliminate the fractions?</h3>

The equation is given as:

-3/4m-1/2=2+1/4m

Rewrite properly as:

$-\frac{3}{4}m - \frac 12 = 2 + \frac 14m$

The denominators of the above fractions are 2 and 4

The LCM of 2 and 4 is 4

So, we multiply through by 4.

This gives

-3m - 2 = 8 + m

Hence, to eliminate the fraction, we multiply by 4
