how do u convert this to slope intercept form step by step and whats the answer?

Slope intercept form is y=mx+b
m=slope
b=y-intercept
You need to get y by itself. Add -20 to each side of equation:
-10y = 30x+20
Divide by -10:
y = -3x-2
And there you go.

-10y-20=30x
-10y-20=30x
+20 +20 Add 20 to both sides of the equation
-10y= 30x+20
-10y= 30x+20
Divide each side by -10 to get y alone. You are then left with
y= -3x-2

-10y=30x+20 add 20 to both sides
y= -3x-2 divide by 10

-10y - 20 = 30x
add 20 to both sides
-10y = 30x + 20
divide by -10
y = -3x + 2

first, reduce y: (divded by -10 on both sides)
-10y -20 =30x
-
-10 -10
then you have: y - 20 = 30x
now get rid of 20 on y's side
y - 20 =30x
+20 +20
Now you have: y=30x +20!

slope intercept form is y = mx + b
where m is the slope of the line, and b is the y-intercept.
At this point, put your equation in this format, do the math to simplify BOTH sides of the equation, and you will have your answer.

wow i cant even believe im doing this haha butt here...
y=2+3x
sorry if this is wrong!
