Answer:
1
Step-by-step explanation:
The y-coordinate is 4, so we count 4 units up the y-axis from the x-axis. You can also look at it as counting 4 units up from the origin. Then, we look at graph C. When y=4, when we're 4 units above the x-axis, x=1 since the point on the line falls 1 unit to the right of the y-axis.
I hope this helps!
Answer: Option A
Step-by-step explanation:
To get from A to A', what is done?
A is at the point (2,6) and A' is at the point (2,-1)
The x value of the two points stayed constant (didn't change) meaning that options C and D are invalid (because those two are transformations to the x-value)
Now let us take a look at options A and B which both concern the y value
The y-value of A is 6 and A' is -1
To get from 6 to -1, do you
a) subtract 7
or b) = multiply by -1
Let us test it out:
a) 6 - 7 = -1 (yes, it equals -1)
b) 6 * -1 = -6 (no, it does not equal the intended value of -1)
Thus correct choice is A, we subtract 7
So you want the circumference?
ANSWER

EXPLANATION
We want to find the equation of the straight line given on the graph.
The general form of a linear equation is given as:

where m = slope; b = y-intercept
To find the slope, we apply the formula for slope:

where (x1, y1) and (x2, y2) are two points on the line
Let us pick (1,2) and (4,4)
Therefore, the slope is:

To find the equation, we now apply the point-slope formula:

Therefore, we have that the equation of the line is:

That is the equation of the line.
