A1 Unit 2 Flashcardziz

Front

What is the slope of the line represented by the equation y = -x + 4?

Back

The slope (m) is -1.

Front

What is the y-intercept of the line represented by the equation y = -x + 4?

Back

The y-intercept (b) is 4.

Front

Write the linear inequality in standard form for a budget of no more than $81, where breadsticks cost $7 and pizza costs $13.

Back

7x + 13y ≤ 81.

Front

What inequality represents the graph where x is less than -1?

Back

x < -1.

Front

Why do parallel lines never intersect?

Back

Because they have the same slopes.

Front

Solve for y in the equation 5x - y = 16.

Back

y = 5x - 16.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

Define a linear inequality.

Back

An inequality that describes a region of the coordinate plane, typically in the form Ax + By < C or Ax + By > C.

Front

What does the y-intercept represent in a linear equation?

Back

The point where the line crosses the y-axis.

Front

How do you determine if two lines are parallel?

Back

If they have the same slope.
