Front

If a system of equations has no solution, what does the graph look like?

Back

The graph consists of parallel lines.

Front

Write the equation of the line with a slope of -3/2 and a y-intercept of 4.

Back

y = -3/2x + 4

Front

What is the value of (3/4)^0?

Back

1

Front

Is the function represented by the table linear or nonlinear?

Back

Linear

Front

Who has the greater rate of change if Troy's rate is 5 and Lucy's rate is 3?

Back

Troy has the greater rate of change.

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

The slope is 3/2.

Front

What does it mean for two lines to be skew?

Back

Skew lines are lines that do not intersect and are not parallel.

Front

What is the y-intercept of the line y = 2x + 5?

Back

The y-intercept is 5.

Front

How do you determine if a function is linear from a table of values?

Back

If the rate of change between the values is constant, the function is linear.

Front

What is the formula for the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1)
