-1/5

Front

Write the equation for the line in slope-intercept form if the slope is 4 and the y-intercept is 3.

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

How do you find the slope of a line given two points?

Back

Use the formula: slope = (y2 - y1) / (x2 - x1).

Front

What does it mean for a system of equations to be consistent?

Back

It has at least one solution.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the definition of the y-intercept?

Back

The point where the line crosses the y-axis.
