A.

`y = -3x + 29`

B.

`y = 3x + 13`

C.

`y = (1)/(3)x− 29`

D.

`y = -(1)/(3)x− 13`

Answer

A.  'y = -3x + 29`

Step by step explanation

The given information are slope (m) = -3 and passes through the point (7, 8)

Let's use the slope-intercept form y = mx + b

Here m = -3, plug in the value in the slope-intercept form.


y = -3x + b which is passes through point (7, 8)

To find the slope intercept, plug in x = 7 and y = 8 in the above equation, we get

8 = -3(7) + b

b = 8 + 21

b = 29

Now we got m = -3 and b = 29

Therefore, the required equation y = -3x + 29
