Undefined Slope. Through (97 , 73)

Mnenie [13.5K]

Answer:

Equation of line through ( $(x_{1},y_{1})$ ) having undefined slope is given by

$\frac{y-y_{1}}{x-x_{1}}=tan\alpha$ where α =90°

Now ,it is given that line passes through (97, 93)

So , equation of line is

→ $\frac{y-73}{x-97}$ = tan 90°

As, tan 90°=1/0

$\frac{y-73}{x-97}=\frac{1}{0}\\$

→ (x-97)×1= (y-73)×0

→ x-97 =0

→ x=97 , which is the required equation of line.

arlik [135]

Answer:Bottle B

Step-by-step explanation:

Given

Bottle A has 175 fluid ounce and cost $\$19.25$

So it cost $\frac{175}{19.25}=9.09\ \text{ounce per}\ \$$

Bottle B has 138 fluid ounce and cost $\$8.97$

So it cost $\frac{138}{8.97}=15.38\ \text{ounce per}\ \$$

Bottle C has 100 fluid ounce and cost $\$8.0$

So it cost $\frac{100}{8}=12.5\ \text{ounce per}\ \$$

Bottle D has 72 fluid ounce and cost $\$7.56$

So it cost $\frac{72}{7.56}=9.52\ \text{ounce per}\ \$$

So, Bottle B delivers more ounces at same price
