Lesson 1-4
1. Joann can write 4 problems in 3 minutes. At
this rate, about how long will it take her to write
8 sets of 5 problems?
8 x 5 = 40
Be careful….not all rate problems are set up to solve.
Make sure you know exactly how many
problems

3. Which expression represents the perimeter
of the isosceles triangle below, in terms of x?
An isosceles triangle
has 2 congruent sides
and two congruent
angles.

2x + 5

½(x2 + 5x)
3x + 10
To find perimeter, find the
sum of all sides.
Only combine like terms!
Triangles have 3 sides…
The missing side has a length of x + 5
This used the AREA formula
Correct Answer!
4. Find the slope of the linear equation:
12x – 4y = 24
Slope is the rate of change,
To find slope, m, from standard form
and often called rise/run
[ax + by = c], use the formula m = -a/b
It might be easier to remember to say
“opposite of x over y”

In slope-intercept form [y = mx + b], the
coefficient on the x is the slope!

In standard form, the coefficient on the x is not the slope
OPPOSITE of x over y: -12/-4 = 3
Correct Answer!
When finding slope, the constant (24) should not be used
