can you check my answers?
i have to write the slope intercept form of the equation
key (a= means answer is)
1. 3x-2y=12
a= 3/2x-6=y
2. x+y=7
a= y=-x+7
3. -13+6y=x
a= y=x/6+13/6
4. -2y=24+6x
a= y=-3x-12
5. 49x-y=558
a= y=49x-558
6. 3x+14y=-56
a= y=-3/14x-4
7. -1/6y-1/6=x
a= y=-1/6x-1
8. 10x-3y=56
a= y=-10/3x+56/3
9. -13/6=-1/6y+x
a= 6x+13=y
10. -14x=1322+48y
a= =7/24x-661/24=y
11. 9x+16y=528
a= y=-9/16x+33
12. 18x=636+38y
a= 9/19x+318/19=y
13. 2x+15y=-402
a= y=-2/15x-134/5
14. x=4-5/4y
a= -4/5x-16/5=y
15. 8x+3y=1
a= y=-8/3x+1/3
16. 7x-2y=-39
a= y= 7/2x+39/2
17. 7/3y-7=x
a= y= 3/7x+3
18. 9x-50y=167
a= y=9/50x-167/50

To check your answers for writing the slope-intercept form of the equations, we need to make sure that each equation is in the form "y = mx + b," where "m" represents the slope and "b" represents the y-intercept. Let's check each equation:
1. 3x - 2y = 12
To write this equation in slope-intercept form, isolate y:
-2y = -3x + 12
Divide the entire equation by -2 to solve for y:
y = (3/2)x - 6
Your answer is correct: y = (3/2)x - 6
2. x + y = 7
To write this equation in slope-intercept form, isolate y:
y = -x + 7
Your answer is correct: y = -x + 7
3. -13 + 6y = x
To write this equation in slope-intercept form, isolate y:
6y = x + 13
Divide the entire equation by 6 to solve for y:
y = (1/6)x + 13/6
Your answer is correct: y = (1/6)x + 13/6
4. -2y = 24 + 6x
To write this equation in slope-intercept form, isolate y:
-2y = 6x + 24
Divide the entire equation by -2 to solve for y:
y = -3x - 12
Your answer is correct: y = -3x - 12
5. 49x - y = 558
To write this equation in slope-intercept form, isolate y:
-y = -49x + 558
Multiply the entire equation by -1 to solve for y:
y = 49x - 558
Your answer is correct: y = 49x - 558
