What are the points for -3x+6y+5=-7

1 answer:

7 0

-3x + 6y + 5 = -7
 -5 -5
 -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
6y = -12 + 3x
6 6
y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3x + 3x - 12 = -12
0x - 12 = -12
 +12 +12
 0x = 0
 0 0
 x = 0
-3(0) + 6y = -12
0 + 6y = -12
+0 +0
 6y = -12
 6 6
 y = -2
(x, y) = (0, -2)

What is the equation of a line passing through (-3,7) and having a slope of -1/5 PLEASE HELP

OLEGan [10]

Answer:

y = -1/5x +32/5

Step-by-step explanation:

The slope intercept form of the equation of a line is

y = mx+b

we know m = -1/5

y = -1/5x+b

We know a x and y on the line

7 = -1/5(-3) +b

7 = 3/5 +b

Subtract 3/5 from each side

35/5 -3/5 = b

32/5 =b

So the equation is

y = -1/5x +32/5
