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

Front

For the equation y - 3 = 2(x + 4), what point does the line contain?

Back

(-4, 3)

Front

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

Back

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

Front

Convert the equation y = mx + b to point-slope form.

Back

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

Front

What does the y-intercept represent in a linear equation?

Back

The value of y when x = 0.

Front

If a line has a slope of 2, what does this indicate about the line's steepness?

Back

The line rises 2 units for every 1 unit it runs to the right.

Front

What is the slope of a vertical line?
