Answer:
y = 4x - 9
or y = 4x + -9
Step-by-step explanation:
First, you must find a point that intersects with the line
The point that intersects the line is: (3,3)
Second, you must do rise over run, to find out how far one point is from the other
Rise over run consists of the rise (the change in y, going up or down) divided by the run (the change in x, going from left to the right).
So, for this question, the slope would be up 4 and to the left 1 or 4/1 = 4
Then we must find the y-int
The y-int is the number that intersects the y-int
So, for this question it would be -9
You can't see the whole graph in the picture, but you can kind of see it intersect the number -9
So, we must put together the equation, which is y = mx + b
m = slope = 4
b = y-int = -9
So, the equation would be: y = 4x - 9 or y = 4x + -9
here is a graph with the equation
and another graph with rise over run

Answer:
1.49 hrs or 1 hr and 30 minutes approximately
Step-by-step explanation:
if fran go 2.8m up then the river flow at a rate of 0.8m; the since we are taking the speed of fran and river to be constant. the ratio between their speed will always remain constant. that is if 0.8/2.8 = 0.286≈ this will be always constant.
so if he go up 4m then the horizontal length has to be 1.143 because 1.143/4 = 0.286.
now we find the distance between frans initial positon and final position. to find it we use pythagoras theorem.
to find the time divide distance traveled by speed;
4.160/2.8 = 1.49 hrs
The equation of the function is F(x) = -3(x-4)² +4 , the correct answer is Option D
The missing graph is attached with the answer
<h3>What is a function ?</h3>A function is a law that relate the independent variable and the dependent variable.
It is given that
The graph of F(x), shown below, resembles the graph of G(x)= x², but it has been changed
From the graph, it is seen that,
G(x) when shifted by -4 on the negative x axis.
and graph shifted by +4 on the positive y axis.
F(x) is scaled by a factor of -⅓ of G(x)
it is reflected across the x-axis.
So the equation of the function is
F(x) = -3(x-4)² +4
Therefore , the correct answer is Option D.
