r/3 + t = w to get r by itself (Which I think is your question)
r/3 + t = w subtract t from both sides
r/3 = w - t and times by 3 on both sides
r = 3(w-t)
C is true because the slope for johan is 15 compared to Rowans slope which is 5
Answer:
Step-by-step explanation:
Slope-intercept equation of a line is,
y = mx + b
Here, m = Slope of the line
b = y-intercept
If m = -6 and b = 3,
Equation of the line will be,
y = -6x + 3
Input - output values got the graph of this line,
x -1 0 1 2
y 9 3 -3 -9
Now by plotting these points we can draw the line on graph.
<u>Given:</u>
It is given that the value of the graph when the input 7 is 
We need to determine the value of x when 
<u>Value of x when </u>
<u>:</u>
The value of x can be determined by using the graph.
From the graph, we need to determine the value of x when
other than the value x = 7.
This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.
Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.
Therefore, the input value is x = -8 which makes 
Hence, the input value other than 7 for which
is x = -8.
