Please answer this question Thank you !!

D

Step-by-step explanation:

Plug in the coordinates and find out!

a. 5=9+14 This is wrong so a is not and option

b. 5=9-14 also wrong

c. 5=-9-14 also wrong

d. 5=-9+14 This is right! Plug in the other coordinates -1=-15+14

IT works!

D

Step-by-step explanation:

To find the equation, we will find the slope and y-intercept. To find the slope, you would use the formula .

Now that we have found our slope, we can plug m into the slope-intercept form and solve for b, y-intercept.

y=mx+b

y=-3x+b

Solve for b, y-intercept. We can plug in any pair given to find b.

5=-3(3)+b

5=-9+b

14=b

We have our m and b, our final equation is y=-3x+14.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
