His brother would be 7 years old.
Answer:
-2
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( -2-6)/(2- -2)
= ( -2-6)/( 2+2)
-8/4
-2
1
When the input is 0 (horizontal axis), the output is 1 (vertical axis).
The sum of the angles equals 180
therefore
x+(1/4x)=180
1 1/4 x = 180
x=180/ 1 1/4
x=144
1/4 x =1/4(144)=36
<span>{(–1, 3), (5, 3), (–6, 7), (9, 0)} is the correct answer.
