In the figure we can identify 2 rays and a point of intersection between them
So the anwer is (b) two rays and an intersecting point
If L is the line having x -intercept of -1 and y -intercept of 3, complete the equation of L . y = -x + 3 y = -3x + 3 y = 3x + 3
1 answer:
Answer:
y = 3x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← x and y- intercepts
m = =
= 3
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = 3x + 3 ← equation of line

Step-by-step explanation:
Given
<u>Circle C</u>
--- radius
--- center
<u>Circle E</u>
--- center
Required
Prove their similarity
Translate circle C 8 units up;
The rule is:
So, we have:
Translate circle C' 7 units right;
The rule is:
So, we have:
<em>At this point, both circles now have the same center at (4,9)</em>
The next step is to dilate circle E by 4/3
This will only affect radius and not the center of E
The rule is:
So, we have:
-- equal radii
--- equal center
