Question 29037: Any assistance would be great! Please help.
3. Solve the system by addition.
–4x + 5y = 1
x – 4y = 19

6. Find the slope of the line passing through the points (–4, 1) and (–4, 4).
{{4-1/-4--4}}
Undifined because the Denomator is 0

15. Solve the system.
5x – 3y = 13
4x – 3y = 11


16. Solve for c. a = 1/2 bc^2
2a=bc^2
2a/b=c^2
sqaure root of 2a/b=c


17. Solve the system.
x + 2y = –15
–2x + 4y = 6


28. Rewrite the equation y = 4x – 1 as a function of x.
y+1=4x
y+1/4=x


33. Write the equation of the line that passes through point (0, 7) with a slope of 8/3.
y=mx+b
7=8/3(0)+b
7=b
y=8/3x+7
