Answer:

Option B

Step-by-step explanation:

Slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

Slope (m) = \frac{y_2-y_1}{x_2-x_1}

Therefore, slope of the line passing through (-5, -2) and (3, -1) will be,

m = \frac{-1+2}{3+5}

m = \frac{1}{8}

Equation of the line passing through (h, k) and slope 'm' is given by,

y - k = m(x - h)

Therefore, equation of the line passing through (3, -1) and slope = \frac{1}{8} will be,

y+1=\frac{1}{8}(x-3)

y=\frac{1}{8}x-\frac{3}{8}-1

y=\frac{1}{8}x-\frac{11}{8}

Option B will be the answer.

-4 + 3y = -43<br> what does y equal?
NeTakaya

Answer:

-13

Step-by-step explanation:

We remove the -4 by adding 4 to each side:

3y = -43 + 4

Now we simplify to give:

3y = -39

So now we divide both sides by 3 to give our answer of:

y = -39/3
y = -13
We can substitute this into the original equation to check our answer:

-4 + 3(-13) = -43

-4 + -39 = -43

The perimeter of a rectangle is 20 inches.The length is 2 inches less than twice the width.
SSSSS [86.1K]

Answer:

width = 6

length = 4

Step-by-step explanation:

perimeter = 2L + 2W

L = W - 2

plug in perimeter:

20 = 2L + 2W

you know the length is 2 less than the width

plug in (w - 2) for L:

20 = 2(w - 2) + 2w

solve for w:

20 = 2w - 4 + 2w

20 = 4w - 4

4w = 24

w = 6

now plug in 6 for w in either equation, whichever is easier to solve:

L = 6 - 2

L = 4

width = 6

length = 4

Leanne multiplied 8 x 4.3 and got 32.24. Is Leanne correct?Use an area model to explain your answer
dlinn [17]

Answer:

No, not correct.  

Step-by-step explanation:

Note that 8 * 4.3 can be broken up as follows:

8 * (4 + 0.3)

and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).

Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4
