9) 7x – 3y = 21
Steps :
1. Look to see if it is in slope intercept form (y=mx+b)
2. If not get rid of the x’s first by doing the opposite operation (add
or subtract them)
3. Then solve for y by doing the opposite operation (multiply or
divide)to get rid of the # in front of y.
4. Write in slope intercept form.
5. Name the slope (m) and the y-int. (b)
10) y = 4x + 6
2
11) 8(x + y) = 32
Steps :
1. Look to see if it is in slope intercept form (y=mx+b)
2. Use distributive property
3. If not get rid of the x’s first by doing the opposite operation (add
or subtract them)
4. Then solve for y by doing the opposite operation (multiply or
divide)to get rid of the # in front of y.
5. Write in slope intercept form.
12) 2(x – 3y – 2) = 8
6. Name the slope (m) and the y-int. (b)
