It would be b. the first ratio is

so you would match up the kL and not know how many regular liters there are.
8kL

Yes as long as one side on a square is the same on another they are the copies of each other
Answer:
or 
Step-by-step explanation:
The perpendicular slope is the opposite-reciprocal of the original slope:
Perpendicular slope of -2 is 
Write the equation in point-slope form (
):
Convert to slope-intercept form if needed:
Because a line always goes past the y-intercept and x-intercept. It's not always both, it can sometimes just be the x-intercept or the y-intercept.
When a line intersects these points, for example if a line was to intersect the x-axis then y would be equal to 0, and the opposite for the y-axis. If a line was to intersect the y-axis x would be equal to 0.
Therefore by using that knowledge, and the equation of the line [ y=mx+c or y-y1=m(x-x1) ], we can find the equation of our line. Of course you would need the gradient of that line (the value "m").
