Front

Write the equation of a linear function, in slope-intercept form, that is perpendicular to y=4x-1 and passes through the coordinate (-12, -4).

Back

Which scatter plot shows a linear relationship between x and y?

Back

Graph C

Front

Write the equation of a linear function, in slope-intercept form, that is parallel to y=\frac{1}{3}x+2 and passes through the coordinate (-12, 9).

Back

y=\frac{1}{3}x+13

Front

What is a function?

Back

A relation where each input has exactly one output.

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

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are negative reciprocals of each other.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope.
