1) Slope tell about the steepness of the line.
To find slope we look at the rise and run between 2 points.
attached the graph of line with slope
slope = 
= 
So slope = 2
2) we have x and y intercepts
x intercept is the point where the line crosses x axis
x intercept at x= 3
y intercept is the point where the line crosses y axis
y intercept at y= 6
3) Linear equation is y= 3x+2
function is f(x) = 3x+2
We can graph it using slope and y intercept
In f(x)= 3x + 2 , slope =3 and y intercept = 2
slope = 3, rise = 3 and run =1
The graph of f(x)= 3x+2 is attached below.
Answer:
Yes
Step-by-step explanation:
It passes the vertical line test.
if you draw vertical lines, it should hit the function only once, if it hits coordinates with the same x value (for example, (1,2) and (1,3)), it is not a function.
In the graph, each x value is only hit once.
I’m pretty sure it’s 9, I haven’t done this in awhile though...
we are given
y varies directly with x
so, we can write equation as

where
k is a constant
now, we need to find k
we are given
y=3 when x=8
so, we can plug it and find k


now, we can plug it back

(A)
we have got equation as

for finding inverse , we can switch x and y

now, we can solve for y


............Answer
(B)
we have

we can plug x=4 and find y
