Front

What is the formula to find the slope of a line using rise/run?

Back

Slope = rise/run

Front

Write the equation in point-slope form of the line that passes through the point (4, -7) with a slope of -1/4.

Back

y + 7 = -1/4(x - 4)

Front

Back

Slope = 5

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b

Front

How do you convert the slope-intercept form to standard form?

Back

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

Front

Front

How do you find the y-intercept from a linear equation?

Back

Set x = 0 and solve for y.

Front

What is the point-slope form of a linear equation?

Back

y - y1 = m(x - x1) where (x1, y1) is a point on the line.
