Answer:
-3,3
Step-by-step explanation:
the line reaches at the point -3 at the bootem and the top reaches 3 so how i know it would be 3 ,-3 bc the 3 is at the top and -3 is at the bottem
Given function is a direct variation
Step-by-step explanation:
The direct proportion is defined as the increase in one quantity causes increase in other quantity.
If y is directly proportional to x, then it is given as:
y = kx
where k is the constant of proportionality
Given
y = 3x
Comparing the general form and given equation we see that both are same where k =3
So,
Given function is a direct variation

Answer:
x=40°
Step-by-step explanation:
(x-5)+(x+15)=90°
2x+10=90
2x=80
x=40°
Answer:
y = 36x
Step-by-step explanation:
Given that y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 18 when x = 
, thus
k = 
= 
= 36
y = 36x ← equation of variation
The only two points that I can clearly see are (0,2) and (5,3).
The slope is (y2-y1)/(x2-x1), in this case:
m=(3-2)/(5-0)=1/5
So the slope of the line is 1/5
