Can someone plz help

Answer:

I think there 1 and 1/2 quarts of lemonade left in the pitcher because in 1 quart there is 4 cups of something. In one gallon there are 4 quarts. So in one gallon there are 16 cups. How I got 16 cups it’s easy (4+4+4+4) . So they drank 5 glasses and each glass is 2 cups. So it will be 10 cups. (2+2+2+2+2). So in one gallon 16 cups they drank 10 cups. 6 cups left. 4 cups one quart and 2 cups is 1/2 of one quart. So the answer is 1 and 1/2 quarts of lemonade. Thank you

L is parallel to y=5x. Write an equation for line L in point-slope form
olga nikolaevna [1]
Point slope is y - Y=m(x-X)  where m is slope and (X,Y) is a given point on the line

so you can get y-Y= 5(x-X) 
and then just choose a point for your parallel line to go through, say (2,3)

so you get y-3 = 5(x-2)
