Answer:
Draw a straight line that goes through the point (0,4) and (20,0)
Step-by-step explanation:
The y-intercept is equal to 4, since the function is already in y=mx+b form, where b is the y-intercept.
To find the x-intercept, we substitute 0 into y or in this case the f(x).
0 = -1/5 (x) + 4
1/5 x = 4
x = 20
The x-intercept is 20.

The equation of the circle with center (0, 1) and a radius of 10 is
<u>Solution: </u>
Equation of circle whose center (h, k) and radius r is given as,
---- eqn 1
From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.
Hence we get, h = 0 ; k = 1; r = 10
By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as
On Simplifying we get
Expand using the formula
Hence equation of the circle with center (0, 1) and a radius of 10 is
