Answer:
y=-2x-12
Step-by-step explanation:
first, putt 3x-6y=2 in standard form:
subtract 3x from both sides: -6y=-3x+2
divide both sides by -6 to isolate y: y=1/2x-1/3
if the other line is perpendicular to this, you must find the slope by finding the opposite reciprocal of 1/2x: -2
now we have 2 points a slope, so we use the point-slope formula: y-y1=m(x-x1)
y+2=-2(x+5)
Use the distributive property: y+2=-2x-10
subtract 2 for both sides to isolate y: y=-2x-12
Answer:
y = 8x - 64
Step-by-step explanation:
Start with y = mx + b, the slope-intercept equation. Replace m with 8, x with 7 and y with -8:
-8 = 8(7) + b, or
-8 - 56 + b, or
b = -64
Then the desired equation is
y = 8x - 64
I’m not sure never took that test
