Solution:
we have been asked to find
The equation of the line that has a slope of 1/4 and a Y intercept of -3.
The standard equation of straight line in the slope-intercept form is given by the formula
where m is the slope of the straight line and b is the y-intercept.
Substitute the given values we get
Hence the equation of the line that has a slope of 1/4 and a Y intercept of -3 is
Answer: The equation is
Center = (-4,4)
Radius = 3
===========================================================
Explanation:
This graph shows the circle's center is at (-4, 4)
Recall in general, the center is (h,k)
So we see that (h,k) = (-4,4). More specifically: h = -4 and k = 4.
The radius of this circle is r = 3 as this is the distance from the center to any point on the edge. For example, go from (-4,4) to (-1,4).
With the h, k and r values in mind, we then say the following:
which represents the equation of this circle.
