Front

What does the point-slope form of a linear equation look like?

Back

The point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

Write the point-slope form of the line with slope -1/4 passing through (4, -7).

Back

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

Front

If two lines have slopes m1 = 5 and m2 = 5, are they parallel?

Back

Yes, they are parallel because they have the same slope.
