What is the equation of a line that passes through points (0, 4) and (-4, -8)?

2 answers:

7 0

The answer is D. you know that the equation must end in +4 as the yintercept is at four (y=4 when x=0)
then you can work out that it is 3x because when x changes by -4, y changes by -12, which is three times as much.
Hope this makes sense!

Slope = (-8 - 4)/(-4 -0) = -12/-4 = 3

y-intercept so b = 4

equation: y = 3x + 4

answer: <span>C. y = 3x + 4</span>

I need help with this question about similar triangles

Colt1911 [192]

Answer:

ST = 12 units

Step-by-step explanation:

Δ RAS and Δ TES are similar triangles, thus the ratios of corresponding sides are equal, that is, noting that SR = 21 - ST, thus

$\frac{ST}{SR}$ = $\frac{TE}{AR}$ substitute values

$\frac{ST}{21-ST}$ = $\frac{8}{6}$ ( cross- multiply )

6ST = 8(21 - ST)

6ST = 168 - 8ST ( add 8ST to both sides )

14ST = 168 ( divide both sides by 14 )

ST = 12

Evaluate y5 + x(-7)<br> When x = 2, y = -5

Ymorist [56]

Answer:

Step-by-step explanation:

OK, first we turn the variables into into the actual values:

The equation will look like this:

(2)5 + (-5)(-7)

Now its easier to solve! Lets solve (2)5!

2 * 5 = 10

The equation looks like:

10 + (-5)(-7)

We will also solve (-5)(-7). Remember that a negative number times a negative number is positive!

-5 * -7 = 35

Lets finish the rest:

10 + 35 = 45.

Hope this is correct and have a nice day!
