Answer:
D) (-2, -9)
Step-by-step explanation:
X( -11, 8)
M(-6.5, -0.5)
-11 - (-6.5) = -11 + 6.5 = -4.5
8 - (-0.5) = 8 + 0.5 = 8.5
To get from Midpoint to endpoint:
(x , y) → (x - 4.5, y + 8.5)
Y endpoint:
M(-6.5, -0.5) → (-6.5 + 4.5, -0.5 - 8.5)
Y( -2, -9)
To help solve this, we need to use the slope formula.
(y2 - y1) / (x2 - x1). We get these values by picking two points on a line.
We will use points (-3, 1) and (-17, 2).
y1 = 1
y2 = 2
x1 = -3
x2 = -17
Let's plug these into our formula.
(2) - (1) / (-17) - (-3) = 1 / - 14
The slope is 1 / -14
-5
Make the equation into slope-intercept form, which is y = mx + b, where m is the slope, and b is the y-intercept.
In the equation y = -5x - 2/3, the slope is -5 and the y-intercept is -2/3.
