Answer:
line r or MB
Step-by-step explanation:
To write the equation of a line I need slope and y intercept (0,y)
I have y intercept (0,7) of +7 as written in the equation
The equation y=-5/4x + 11/4 has a slope of -5/4
To get perpendicular slope is negated reciprocal
so take -5/4 and flip it -4/5 and change the sign (in this case negative to positive) 4/5
so the new equation is y=4/5x +7 (third one)
.08 cents per ounce, because 2.40 ÷30 =.08
Easy. Just add a 0 on the end of the numerator and denomenator.
