Answer: y = -8x + 9

Step-by-step explanation:

The slope intercept form formula says that y=mx +b where m is the slope and b is the y-intercept so input the value for m and b to write the equation.

Answer:

x=5

y=2

Step-by-step explanation:

-3(4х – 9у – 2 = 0)

=-12x+27y+6

12х - 5у + 38

-12x+27y+6

22y=44

y=2

NEED HELP ITS A TEST!

Answer:

X = -2 - y/3

Step-by-step explanation:

First you need to know the current equation, for that:

Notice that when Y = 0, X = 2.

When Y = 6, X = 0

Therefore the equation is X = $2-\frac{y}{3}$

To move that to the left of the X axis (negative direction) you just have to reduce the X number:

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