Answer:
C. ![y = -\frac{1}{2}x - \frac{7}{2}](https://tex.z-dn.net/?f=%20y%20%3D%20-%5Cfrac%7B1%7D%7B2%7Dx%20-%20%5Cfrac%7B7%7D%7B2%7D%20)
Step-by-step explanation:
We can get the equation in slope-intercept form if we know the slope (m) and the y-intercept (b).
Since the line is parallel to -2x + 4y = 8, it will have the same slope as the equation.
Converting -2x + 4y = 8 into the slope-intercept form, we would have:
4y = -2x + 8
y = -2x/4 + 8/4
y = -½x + 2
Theregore, slope, m, of the line that is parallel bro 4y = -2x + 8 is -½.
To find the y-intercept, b, substitute (x, y) = (-5, -1) and m = -½ in y = mx + b.
Thus:
-1 = (-½)(-5) + b
-1 = ⁵/2 + b
-1 - ⁵/2 = b
(-2 - 5)/2 = b
-⁷/2 = b
b = -⁷/2
To get the equation of the line, substitute b = -⁷/2, and m = -½ in y = mx + b.
The equation would be:
![y = -\frac{1}{2}x - \frac{7}{2}](https://tex.z-dn.net/?f=%20y%20%3D%20-%5Cfrac%7B1%7D%7B2%7Dx%20-%20%5Cfrac%7B7%7D%7B2%7D%20)
Answer:
ABCDEFGH
Step-by-step explanation:
Answer:
6x + 5y + 13 = 0.
Step-by-step explanation:
y = 5/6x + 7/6
Gradient = 5/6
Since the line is perpendicular to y = 5/6x + 7/6
then its gradient is -6/5.
Hence its equation is: point (-8,7).
y - 7 = -6/5(x -(-8))
multiplying through by 5 we get;
5y - 35 = -6(x + 8)
5y - 35 = -6x - 48
6x + 5y + 13 = 0
