Algebra I part 1

Front

What does the graph of a system of equations with no solution look like?

Back

The graph consists of parallel lines.

Front

What is the slope of a line?

Back

The slope is a measure of how steep a line is, calculated as the rise over run.

Front

Find the slope of the line between the points (-3, -4) and (7, 6).

Back

The slope is 1.

Front

Solve for x: 3(x+2)=7(8-x)

Back

x=5.

Front

If f(x)=3x-9, what is f(5)?

Back

f(5) = 6.

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

What is the formula for calculating the slope between two points?

Back

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

Front

What does it mean if a line is undefined?

Back

An undefined slope occurs when a line is vertical.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis.
