Answer:
Step-by-step explanation:
y=−2x+5
m= -2
As required line is parallel to y=−2x+5, slope will be same for these two lines.
slope of required line = -2
m = - 2 ; (1, -4)
y - y₁ = m (x - x₁)
y - (-4) = -2 * (x - 1)
y + 4 = -2x + 2
2x - 2 + y +4= 0
2x + y + 2 =0
y = -2x -2
Answer:1250 units
Step-by-step explanation:
circumference=7850
Radius=?
Radius=circumference ➗ (2xπ)
Radius=7850 ➗ (2 x 3.14)
Radius=7850 ➗ (6.28)
Radius=1250 units
Answer:
y = -3x - 1
Step-by-step explanation:
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.
First, we find the slope of the line using the two given points.
m = slope = (y2 - y1)/(x2 - x1) = (2 - (-7))/(-1 - 2) = (2 + 7)/(-3) = 9/(-3) = -3
Now we plug in the slope we found into the equation above.
y = -3x + b
We need to find the value of b, the y-intercept. We use the coordinates of one of the given points for x and y, and we solve for b. Let's use point (2, -7), so x = 2, and y = -7.
y = -3x + b
-7 = -3(2) + b
-7 = -6 + b
Add 6 to both sides.
-1 = b
Now we plug in -1 for b.
y = -3x - 1
Answer:
m=0
Step-by-step explanation:
The slope is m=0 and the Y intercept should be b= -4 .
