How to change 2x-3y=-6 into
Slope intercept form and change that into x and y intercept form and then graph it.

For your 7th grader to change that equation into slope-intercept form he would have to know what one looks like.

Here is what a basic slope-intercept form equation looks like: y = mx + b
Where m is the slope and b is the y-intercept.

So now let's do some basic algebra to make the given equation look like that.
2x-3y=-6 [Isolate the y to the left slide as shown in the slope-intercept form example]
-3y=-2x-6 [Divide both sides by -3]
y = (-2x-6)/-3 [Reduce]
y = 2/3x + 2

This is Miriam the student, so for the slope intercept form I got y=2/3x+2 and that is all that I have is it right

Please ask the student to contact us directly - including any work done for this problem.

This is Miriam I am the student and I only know how to change standard form to slope intercept and I'm not even sure that I got that right but I got y=2/3x+2

The standard form of the equation of st. line is:

n * x + p * y = q ..... where x & y are variables and n, p and q are constants.

Isolate 'y' on to left-hand-side

p * y = q - n * x .......... divide both sides by 'p'

y = (-n/p) * x + (q/p) → y = m * x + c

So here

m = (-n/p) and

c = q/p

Well from there how do you change the slope intercept form into X and y intercept and then plot that onto a graph

THANK YOU SO MUCH!!!!! ?
