-6 1
0 3
6 7
10 9
(2) Plot your points
Draw dots at the coordinates of each point.
(3) Draw the graph
Draw a smooth line through the points.
Extend the line in both directions to the edges of the plot area.
Your graph of y - 3 = ½(x+2) should look like the figure below.
Have a beautiful day!

Use the Pythagorean theorem for calculate the length of CA:
We have
Substitute:
subtract 100 from both sides
ΔADC and ΔACB are similar. Therefore the corresponding sides are in proportion:
We have:
Substitute:
cross multiply
divide both sides by 5
If you mean the length of segment CD, then use the proportion:
Substitute:
highest common factor of 20 and 30=10
