Introduction

Since we all love jokes in Algebra 1A, we figured today would be a great day to review for the Mid-Unit Quiz and laugh a little.

Questions

Question 4

Question 5

The volume of a gas (V) varies directly with the temperature (T) and inversely with the pressure (P).

1/3

Problem: Find the constant of variation (k) when V = 42cm3, T = 84oC and P = 50 mmHg.

k = 42

k = 25

k = 84

Question 5

Harper attempted to write the equation of the linear function with f(2) = 8 and f(6) = -2 in slope intercept form by using the steps below.

1/2

Explain the error Harper made when determining the equation of the linear function.

Harper's slope should have been negative.

Harper forgot the parenthesis and did not distribute.

Harper should have added 2 to both sides of the equation.

Harper attempted to write the equation of the linear function with f(2) = 8 and f(6) = -2 in slope intercept form by using the steps below.

2/2

What should be Harper's equation for the linear function in slope-intercept form?

That's Correct!

HAHA!!

Now that's funny!!
