Algebra 1 SEMESTER 1 FINAL Part 2

Front

What is the y-intercept in the equation y=-4x-5?

Back

-5

Front

Write the equation of the line with a slope of \frac{1}{3} and a y-intercept of -2.

Back

y=\frac{1}{3}x-2

Front

What does the graph of the equation y=\frac{1}{3}x-2 look like?

Back

The graph is a straight line that crosses the y-axis at -2 and has a slope of \frac{1}{3].

Front

Which equation represents a vertical line at x=-5?

Back

x=-5

Front

What is the rate of change of y with respect to x in the equation f(x)=\frac{5}{8}x+3?

Back

\frac{5}{8}.

Front

Define the slope of a line.

Back

The slope is the ratio of the rise (change in y) to the run (change in x) between two points on the line.

Front

What is the formula for the slope between two points (x1, y1) and (x2, y2)?

Back

m=\frac{y2-y1}{x2-x1}.

Front

What does it mean if a line has a slope of 0?

Back

The line is horizontal and does not rise or fall.

Front

What does it mean if a line has an undefined slope?

Back

The line is vertical and does not have a defined slope.

Front

How do you find the y-intercept of a linear equation in slope-intercept form?

Back

The y-intercept is the value of y when x=0.
