Front

Convert the standard form equation into slope-intercept form: 5x - 4y = -20

Back

y = (5/4)x + 5

Front

What is the slope of the following equation: 12x - 6y = 30?

Back

2

Front

Slope can be labeled by what letter?

Back

m

Front

What is the equation of the vertical line that passes through x = 3?

Back

x = 3

Front

A line is perpendicular to y = 2x - 7. What is the slope of this line?

Back

-1/2

Front

What is the slope-intercept form of a line?

Back

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

Front

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

Back

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

Front

What does the 'b' represent in the slope-intercept form?

Back

The y-intercept, where the line crosses the y-axis.

Front

What is the slope of a horizontal line?

Back

0.

Front

What is the slope of a vertical line?

Back

Undefined.
