Three of the vertices of a trapezoid are A(3,‐3) B(12,6) andC(4, 8). the fourth vortex is labeled D. one of its bases is AB what is the equation of the line that includes base CD?

y = x + 4

Step-by-step explanation:

AB is a base of trapezoid.

In trapezoid , one pair of sides are parallel.

In given trapezoid , CD is parallel to AB.

When two lines are parallel then, slopes of lines are equal.

Therefore , slope of CD=1

The equation of line with slope 1 and passing through the point C (4,8) is given by Substitute the values then we get

The equation of line with slope 1 and passing through the point C (4,8) is given by

The equation of line with slope 1 and passing through the point C (4,8) is given by

its 4 because 2 times 2 is 4, if you double the number two you get four
