Answer 1

Hello there!

#7

(-11,5) and (-6,1)

To find the slope m, we need to use the slope formula.

y = mx + b

M is the slope we are looking for

m = $\frac{y2-y1}{x2-x1}$

m = $\frac{1-5}{-6-(-11)}$

$m= -\frac{4}{5}$

B is the y-intercept

Thus,

The correct answer is option B  - 4/5

-----------------------------------------

If we want to graph the equation, we must solve it first. Then from there, we will find out which graph looks like the same. So let's get started!

5x + 2y = -3
8x - 6y = -14

We need to solve 5x + 2y = -3 for x

5x + 2y = -3

5x = -3 - 2y

x = $\frac{-2y - 3}{5}$

Now we need to substitute -2/5 y + -3/5 for x in 8x - 6y =-14

8x - 6y = -14

8( -2/5 y + -3/5) - 6y = -14

-46/5 y + -24/5 = -14

-46/5 y = -14 + 24/5

-46/5 y = -46/5

y = -46/5/-46/5

y = 1

Now since we found the value for y, we can use it to find the value for x. We can do that by substitute 1 for y in x= -2/5 y + -3/5

x = -2/5 y + -3/5

x = -2/5 (1) + -3/5

x = -2/5 - 3/5

x = (-2 - 3)/5

x =-5/5

x = -1

Thus, the answers are x = -1 and y = 1

They didn't ask us for the answer. They asked us to graph it. So we need to look at each graph, and the ones that has -1 and 1 on it should be the answer.

Thus,

The correct graph is option D

Answer 2

$HEY THERE!!$

ANSWER:- 7

AS we know the slope of a line is defined by

M = (y2-y)1/(x2-x1)

As we can see that we have to find the slope of line which is parrallel to the line containing (-11,5) and(-6,1)

Here x1 = -11 , x2 = -6 , y1 = 5 , y2 = 1

So the slope will be

M =( 1-5)/ (-6+11)
M = -4/5

So the correct answer is option B.

Hope it helps you.
