just put it into the form y=mx+b. m will be the slope and b willbe the intercept. so:
y=(2/3)x+7
so slope is 2/3
and intercept is 7

-2x+3y=21
implies
y = (2/3)x + 7
compare with y = mx +c
slope = m = 2/3
y-intercept = c = 7

OK. I'll do it step by step. You need to put it in y= mx + b.
1. -2x + 3y = 21
2. 3y= 21 + 2x 1st you need to add 2x to both sides.
3. y= 7 + x Then divide by 3.
4. y- intercept: 7 b= y- intercept. In this case b is 7.
5. slope: 1 m= slope. In this case its 1.
And Tada your answer.

-2x + 3y = 21
Transpose 2x
- 2x + 3y + 2x = 2x + 21
3y = 2x + 21
Diivide both sides of the equation by 3
3y / 3 = 2x / 3 + 21 / 3
y = 2/3x + 7
