Step-by-step explanation:
The formula of a circumference of a circle with radius <em>r</em>:
Solve for <em>r</em>:
subtitute
multiply both sides by 7
divide both sides by 44
Substitute the values of the circumference from your question:
Answer:
The third is if the alternate exterior angles, the angles that are on opposite sides of the transversal and outside the parallel lines, are equal, then the lines are parallel. And, fourth is to see if either the same side interior or same side exterior angles are supplementary or add up to 180 degrees. :)

Answer:
The rate of change is 1/2 and the y-intercept is 1
Step-by-step explanation:
You can calulate the rate of change by picking two points on the graph and using the slope formula
(y2-y1)/(x2-x1)
so in this example you can use the points (2,2) represeting (x1,y1) and (4,3) representing (x2,y2)
When you plug into the slope formula you get:
(3-2)/(4-2) = 1/2 which is the slope.
The y-intercept is where the line intersects the y=axis and can be seen as the coordinate pair (0, #) where the # is the y intercept. From the graph you can see the y-intercept is 1, but you can aslo solve for the y-intercept using the slope-intercept equation:
y=mx+b
where b is the y-intercept and m is the slope.
so using a slope of 1/2 and a coordinate of (2,2) you get:
y-2=(1/2)(x-2)
y = (1/2x)-1+2
y = (1/2x) + 1
so now the equation is in slope-intecept form and you can see the slope is 1/2 and the y-intercept is 1
