70) perpendicular means you take the number in from of the x and flip it and switch the sign. that number will become your slope (m).
y=mx+b. plug in slope and point
-5=(7/9)(-4)+b. multiply
-5=(-28/9)+b. add over -28/9
b= -17/9. plug b and slope into original equation
y=(7/9)x+(-17/9) get rid of frac by multi by 9
(y=(7/9)x+(-17/9))*9
9y=7x+-17. subtract over 7x
-7x+9y=-17. answer
Same goes for the rest. number 72 the perp slope will be (1/3) and for 74 the answer will be x=-5 (that is a weird case)
subtract 3 from both sides to isolate the variable
Z + 3 -3 = -6 -3
Z + 0 = -9
Z = -9

Answer:
3/4 liter per hour
Step-by-step explanation:
1/2=2/3x (multiply by 3 to get 2x)
1 1/2 = 2x (divide by 2 to isolate)
3/4 = x
3/4 liters per hour
