Three of the vertices of a trapezoid are A(3,-3), B(12, 6) and C(4,8). The fourth vertex is labeled D. One of its bases is AB.
What is the equation of the line that includes base CD?
y= 4x+1
y=4
y= x-4
y=x+4

2x + 1 < 5 solve the following inequality. then place the correct number in the box provided.

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.
