Answer:
y=-1/3x+5
Step-by-step explanation:
<u>Slope-intercept form</u>
y=mx+b
m => slope
b => y-intercept
<u>Slope</u>
m=(y2-y1)/(x2-x1)=(5-4)/(0-3)=1/(-3)=-1/3
<u>Y-intercept</u>
y=-1/3x+b
5=-1/3(0)+b
5=b
<u>Final equation</u>
y=-1/3x+5
13
Explanation: a^2 + b^2 = c^2
12^2 + 5^2 = c^2
144 + 25 = c^2
/169 = c
c = 13
