If in standard form you mean slope intercept form, then you are looking to create an equation that looks like this:
y = mx + b
So you need to move around the numbers whilst keeping both sides equivalent.
3x - 9 = 7y
7y = 3x - 9
y = (3x)/7 - 9/7
Your answer should look like this:
y = (3x)/7 - 9/7
If this is not what you meant by standard form please comment and I will see if I can adjust the answer.

Answer: y= -2x - 4
Step-by-step explanation:
This is a straight line, so it can be expressed by y = mx + c.
Here c is y-intercept, which means where line cuts the y-axis. We can see from the graph that the line cuts the y-axis at -4.
So, c = -4.
m is slope.
Use slope formula to find m.
m = ( -4 - 0 ) / ( 0 -(-2))
m = -4 / 2
m = -2
Now put values into this equation
y = mx + c
y = -2x - 4
