Answer:
The answer should be C
Step-by-step explanation
I've had this problem before, and know it should most definitely be C.
Hope I helped!
The y-intercept of the line would change but the slope would not.
Slope is the rate of change of a line. If the y-values all decrease the same amount, the rate that the line is changing will not change. For example, let's take the points (5, 6) and (3, 2). The slope is given by (6-2)/(5-3) = 4/2 = 2. Now let's decrease the y-coordinates all by 2:
(5, 4) and (3, 0)
The slope now would be (4-0)/(5-3) = 4/2 = 2.
By changing the y-values the same amount, the amount of difference between them stays the same, and so does the rate of change of the line.
Since we shifted the y-values down, however, this moves the line down on the graph, which will change the y-intercept.
35 x 12= 420 Multiply 35 by 12. that equals 420
Given:
The graph of a line.
To find:
The equation of line and values of m and b. Check whether it is proportional or linear.
Solution:
From the given graph it is clear that, the line passes through (0,4) and (2,0). So, the equation of line is
Adding 4 on both sides, we get
On comparing this equation with slope intercept form, i.e., 
, we get
All lines are linear. If a line passes through the origin then it is proportional.
From the given graph it is clear that the line is not passing through the origin, i.e., (0,0). So, it is linear not proportional.
Therefore, the value of m is -2 and the value of b is 4. The equation of line is . The line linear not proportional because it does not passing through the origin.
We need a denominator in order to put this into a percentage. Unless the denominator is one, in which we can say 666.6666666... percent.
