Keep in mind that the first number in a coordinate is always on the x-axis (the horizontal line) and the second number is on the y-axis (the vertical line).
If the question asks us to plot (-3, 0), we need to find -3 on the horizontal line and find 0 on the vertical line.
Since 0 means that we go 0 units up, we can just plot the point at -3 on the x-axis.
Next, we need to plot (3, 5). First, let's find the first coordinate by locating 3 on the horizontal axis. Now, we need to find 5 up from that point, because our y-coordinate is 5.

Answer:
BA = 22.57
Step-by-step explanation:
perimeter = 60
2BZ + 2ZA = 60
BZ + ZA = 30, BZ = 30 - ZA
tan 25° = 0.4663
0.4663 = ZA/BZ = ZA/(30 - ZA)
multiply both sides by (30 - ZA):
0.4663(30 - ZA) = ZA
simplify:
13.99 -0.4663ZA = ZA
add 0.4663ZA to each side:
13.99 = 1.4663ZA
divide both sides by 1.4663:
ZA = 9.54
BZ = 30 - 9.54 = 20.46
BA² = 9.54² + 20.46²
BA² = 509.62
BA = 22.57
