The Slope-intercept form of a line:
y = mx + b
where m is the slope and (0,b) is the y-intercept
a. y = -1/4x + 6
slope: -1/4
y-intercept: (0, 6)
b. y = -3
slope: 0
y-intercept: (0, -3)
c. -4x + 2y = 16
Isolating y:
[tex]\begin{gathered} 2y=4x+16 \\ y=\frac{4x+16}{2} \\ y=\frac{4x}{2}+\frac{16}{2} \\ y=2x+8 \end{gathered}[/tex]
slope: 2
y-intercept: (0, 8)
