If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula. 
. So our slope is 7/5. The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is 
, choice D from above.
If ABCD is a rectangle, and m∠ADB=55°, what is the value of x?
2 answers:
Answer: OPTION D.
Step-by-step explanation:
Rectangles have four right angles (angles of 90 degrees).
The point of intersection of the diagonals divides each one of them into two equal parts.
Knowing this, we can conclude that:
(Observe the figure)
Therefore, since the sum of the interior angles of a triangle is 180 degrees, we can find the value of "x":
