Answer:
x² + y² = 25
Step-by-step explanation:
(x - h)² + (y - k)² = r²
Centre: origin --> (0,0)
r² = (-5-0)² + (0 - 0)² = 25
x² + y² = 25
Answer:
2
Step-by-step explanation:
Answer
Anything in front of the x. Everything else is irrelevant unless it changes the value of the number in front of the x.
In this case the slope is 2.
New Question
If the equation was given as 3y = 6x - 8, then the slope would be
y = 6/3x - 8/3
y = 2x - 8/3 which turns out to be 2 not 6
Answer:
4
Step-by-step explanation:
First you solve for x
3x-1 = 2x-4+2x-3-2
3x-1 = 4x-5
You get 4 = x
substitute 4 for x
2(4)-4
8-4
=4
