Answer:
Step-by-step explanation:
y = mx +b
m- Slope ; b - y-intercept
1) y = 2x + 5
Slope = 2
y-intercept = 5
2) 2y = 4x - 5
Divide the equation by 2
[tex]\frac{2y}{2}=\frac{4x}{2}-\frac{5}{2}\\\\y = 2x - \frac{5}{2}[/tex]
Slope = 2
y-intercept = [tex]\frac{-5}{2}[/tex]
3) 3x + 6y = 8
6y = -3x + 8
[tex]\frac{6y}{6}=\frac{-3x}{6}+\frac{8}{6}\\\\ y = \frac{-1}{2}x+\frac{4}{3}\\\[/tex]
Slope = -1/2
y-intercept = 4/3
