What is an equation in point-slope form of the line that passes through (-7.1) and (-3.9)?

forsale [732]

Answer:

$y-1=2(x+7)$

Step-by-step explanation:

Point-slope form: $y-y_1=m(x-x_1)$ where a given point is $(x_1,y_1)$ and the slope is $m$

<u>1) Find the slope of the line (m)</u>

Slope = $\frac{y_2-y_1}{x_2-x_1}$ where the given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the points (-7,1) and (-3,9)

$= \frac{9-1}{-3-(-7)}\\= \frac{8}{-3+7}\\= \frac{8}{4}\\= 2$

Therefore, the slope of the line is 2. Plug 2 into the equation as m:

$y-y_1=2(x-x_1)$

<u>2) Plug one of the given points into the equation</u>

We plan either plug in (-7,1) or (-3,9) and it would work either way. Below you can see the equation plugging in the point (-7,1):

$y-1=2(x-(-7))\\y-1=2(x+7)$

Two angels re supplementary. The larger angle is 48 degrees more than the 10 times the smaller angle. Find the measure of each a

evablogger [386]

Supplementary angles are two angles that add up to 180°.

STEP 1:
find the value of x

x= smaller angle
10x + 48= larger angle

Add the two angles above to equal 180.

x + (10x + 48)= 180
combine like terms

11x + 48= 180
subtract 48 from both sides

11x= 132
divide both sides by 11

x= 12° smaller angle

STEP 2:
find the value of the second angle

=10x + 48
=10(12) + 48
=120 + 48
=168° larger angle

CHECK:
12° + 168°= 180°
180°= 180°

ANSWER: The smaller angle is 12° and the larger angle is 168°.

Hope this helps! :)
