U-Haul charges $25 a day
to rent a moving truck
and $2 per mile.
A) Write an equation that gives total cost as a
function of the distance (miles).
B) What is the cost to rent the truck if I travel 40
miles in 1 day?
+
A) y = 2x + 25
B) y = 2(40) + 25
= $105

+
Write an equation of the line
that passes through the given
point and is perpendicular to
the given line:
(8, -1); y = 2x - 6

Remember
to use the OPPOSITE AND
RECIPROCAL SLOPE!!
+
Write the equation of a
horizontal line that
passes through the point:
(2, 14)
+
y = 14
Remember, the slope is 0… so the
equation is: y = 0x + 14, BUT! you can
simplify that!!
+
Write an equation of the line
that passes through the given
point and is parallel to the
given line:
(2, 5); y = 4x + 9
+
y = 4x – 3
**Steal the Slope: 4
+
Write the equation for a linear
function f with the given values:
f(-2) = 4 and f(6) = 12
+
y=x+6
Remember, 1 is the invisible
number for multiplication!
+
Write an equation of the
line that passes through
the given points:
(6, -5) and (6, 10)
+
x=6
**the slope is undefined!!
+
Write the equation in slopeintercept form:
10x – 5y = 20
+
y = 2x – 4
**Solve for y!!
