Front

What is the solution to the equation y = 5x?

Back

(1, 5)

Front

What is the equation of a line with a slope of 2/3 and a y-intercept of -3?

Back

y = 2/3x - 3

Front

How does the equation f(x) = x change if g(x) = 1/2x + 11?

Back

Vertical shrink and shift up 11

Front

Find the equation of the line that passes through the points (-4, -2) and (-3, 5).

Back

y = 7x + 26

Front

What do the lines y = 5/7x + 2 and y = 5/7x - 30 represent?

Back

Parallel

Front

Define slope in the context of a linear equation.

Back

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

Front

What is the y-intercept of a line?

Back

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

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
