Answer:
y = -2x -5
Step-by-step explanation:
The line crosses the y-axis at -5. So, b = -5.
It goes down 2 units for each 1 unit to the right, so has a slope of ...
m = rise/run = -2/1 = -2
__
The slope-intercept form of the equation of a line is ...
y = mx +b where m is the slope and b is the y-intercept
For the slope and y-intercept shown, the equation is ...
y = -2x -5
Step-by-step explanation:
8x + x² - 2y + y² - 64 = 0
(x + 4)² + (y - 1)² - 81 = 0
(x + 4)² + (y - 1)² = 81
Hencr the center is (-4,1) and the radius is 9.
It would be in the first quadrant since the second quadrant is on the other side of the y-axis.
Answer: 294
Step-by-step explanation:
81-25+800/2=
81-25+400=
81-375= 294
A^2 - b^2 = (a+b)(a-b)
answer :
t^2 - 1
n^2 - 225
