Algebra 1 Unit 3.1 Practice

A. Determine whether y = 4x – 5 is a linear equation. Write the equation in standard form.

• linear equation; y = 4x – 5

• not a linear equation

• linear equation; 4x – y = 5

• linear equation; 4x + y = 5

B. Determine whether 8y –xy = 7 is a linear equation. Write the equation in standard form.

• not a linear equation

• linear equation; 8y – xy = 7

• linear equation; 8y = 7 + xy

• linear equation; 8y – 7 = xy

ANALYZE TABLES Jules has a gas card for a local gas station. The table shows the function relating the amount of money on the card and the number of times he has stopped to purchase gas.

A. Determine the x- and y-intercepts of the graph of the function.

• x-intercept is 5; y-intercept is 125

• x-intercept is 5; y-intercept is 5

• x-intercept is 125; y-intercept is 5

• x-intercept is 5; y-intercept is 10

ANALYZE TABLES Jules has a gas card for a local gas station. The table shows the function relating the amount of money on the card and the number of times he has stopped to purchase gas.

B. Describe what the y-intercept of 125 means in the previous problem.

• It represents the time when there is no money left on the card.

• It represents the number of food stops.

• At time 0, or before any food stops, there was $125 on the card.

• This cannot be determined.
