Yes the expression has like terms. Because 2b and 5b both have the variable b we can add the two coefficient together without the changing the variable. So 2b+5b can become 7b

The y-intercept is where the graph goes through the y-axis (the vertical line in the center). It goes through at y=-9, so the coordinates would be (0,-9), since it is (x,y).
Answer:
-1/4
Step-by-step explanation:
The slope-intercept form is y
=
m
x+b
,
where m is the slope and b is the y-intercept.
y
=
m
x
+
b
Using the slope-intercept form, the slope is 4.
4 m

The equation of a perpendicular line to
y
