Equation 1. 2x+2y=6

y=3x+11

Equation 2. 2x-6y=8

y= -1/3x+2

Equation 3. 6x+8y=4

3x-5y=11

Equation 4. 3x+5y=-18

4x-2y=2

Equation 5. 3x-2y+2z=5

x+2y-z=2

4x-y+3z=11

Equation 6. slope= -3 through (4,-2) in slope intercept form

Equation 7.Perpendicular to -2x+3y=12 through (-4,-5) in standard form

Equation 8. x intercept of 6 through (-2,5) in slope intercept form

Can anyone show me how to do these or atleast do one of each type like do number 1 number 4 number 6-8
