we need to remember the form of the equation line
[tex]y=mx+b[/tex]m is the slope
b is the y-intercept
Base on the form we can assume them
a) y=3x +5
m= 3
b=5
b)
[tex]y=\frac{5}{-4}x[/tex]m= -5/4
b= 0
c) y=3
in this case, we have a horizontal line we can't follow the equation form so easily we must know all the horizontal lines will have m=0.
m=0
b=3
d) y =7+4x
m=4
b=7
Remember the slope is always multiply by x
