Find slope
(y2-y1)/(x2-x1) is slope
(11-3)/(1-(-1))=8/2=4
y=4x+b
input a point
(1,11)
x=1
y=11
11=4(1)+b
11=4+b
minus 4 from both sides
7=b
the equatin is
y=4x+7
the closest one
minus 4x from both sides
y-4x=7
times everybody by -1
4x-y=-7
last choice is answer
Answer:
x=5
Step-by-step explanation:
PYTHAGREOM THEREOM
12^2+b^2=13^2
b^2=25 square
b=5
72 - 55 = 17
(17/55) x 100
= 1700/55
= 30.90909...
= 30.9% (3sf)
