Which equation represents the line that passes through the points (-1,-2)and(3,10)

aalyn [17]

Answer:

Step-by-step explanation:

(-1,-2) , (3,10)

slope(m) = (10 - (-2) / (3 - (-1) = (10 + 2) / (3 + 1) = 12/4 = 3

y = mx + b

slope(m) = 3

u can use either of ur points....

(3,10)....x = 3 and y = 10

sub into the formula and find b, the y int

10 = 3(3) + b

10 = 9 + b

10 - 9 = b

1 = b

so ur equation is : y = 3x + 1

Solve and show your work for each question.

Harlamova29_29 [7]

Answer:

9/20

Step-by-step explanation:

You set the fraction up at first as 45/100. Then you know that 5 goes into each so you divide by 5 $\frac{45}{100} /5$

45/5=9

100/5=20

You get 9/20, and this is in simplest form.

Tomtit [17]

Answer:

Step-by-step explanation:

The area for a triangle is

$A=\frac{1}{2}bh$

Our base is given as x, the height is given as 1 more than 6 times the base which looks like this: 6x + 1. We know that the area is 13, so filling in everything:

$13=\frac{1}{2} (6x+1)(x)$

We can get rid of the denominator of 2 by multiplying it on both sides to get:

$26=(6x+1)(x)$ and simplifying a bit:

$26=6x^2+x$

Now we can move over the 26 and put the expression into standard quadratic form by setting it equal to 0:

$6x^2+x-26=0$ which is choice C
