The center of a circle is at (4,-3) and it’s radius is 3 units, which point lie on the circle

Mathematics
1 answer:
sergey [27]3 years ago
4 0

Answer:

Any set of (x , y) whose distance from (4, -3) is 3 units lies on the circle.

Step-by-step explanation:

To find the distance , use the formula

distance = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}

If distance < 3, (x, y) lies inside the circle.

If distance > 3, (x, y) lies outside the circle.

If distance = 3 (x, y) lies on the circle.

Consider the graph of the linear equation 2x-5y=10. What is the x-intercept? What is the y-intercept? What is the slope?
GenaCL600 [577]
Hey there!

This linear equation is written in standard form, a form in which it's quite easy to find intercepts for one main reason. This reason revolves around zeros. When you see an x intercept, there's always a zero for the y, and when there's a y you see a zero for the x. Therefore, we can do this to get the intercepts.

For x:

2x-5(0) =10
2x = 10
x = (5,0)

For y:

2(0) -5y = 10
-5y=10
y= (0,-2)

Now, to find the slope, we can easily convert it to slope intercept form:

y = mx+b

Where m is the slope and b is he y intercept.

2x-5y=10
-5y=-2x+10
y = 2/5x-2
(notice how we divided both sides by -5)

Therefore, our slope is 2/5. Hope this helps!
