Answer:
y = x + 1
Step-by-step explanation:
Since slope is 1, then the equation will be formatted as y = x+b, since m is 1. Now we need to solve for b, since we're given a coordinate that is on the line, replace x and y for these two points to solve for b.
y = x + b (subsitute)
-1 = -2 + b (add 2 to both sides)
1 = b
So your final equation is y = x + 1.
Answer:
1) Centre: (-4,-8)
Radius: sqrt(93)
2) y = ¼x² - x + 4
Step-by-step explanation:
1) 4x² + 8x +4y² +16y -13 = 0
h = -8/2 = -4
k = -16/2 = -8
(-4)² + (-8)² - (-13) = r²
r² = 93
r = sqrt(93)
sqrt: square root
2) h = (0+4)/2 = 2
y = a(x - 2)² + k
4 = a(0-2)² + k
4 = 4a + k
k = 4 - 4a
12 = a(8-2)² + k
12 = 36a + k
12 = 36a + 4 - 4a
8 = 32a
a = ¼
k = 4 - 4(¼) = 4 - 1 = 3
y = ¼(x - 2)² + 3
y = ¼(x² - 4x + 4) + 3
y = ¼x² - x + 1 + 3
y = ¼x² - x + 4
