Recall that the slope formula is y=mx+b (m is the slope)

You need to first get y by itself, to do that you subtract 9x on both sides of the equation

9x+7y=10 subtract 9x to the left side where it will cancel it because you're adding a positive to a negative number that are the same, then you subtract 9x to the right side of the equation

when you do that you should get: 7y= -9x+10

Now you divide 7 on both sides

you then should get: y= -9/7x-10/7

Answer:

Step-by-step explanation:

using sine formula

$\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c} \\\frac{sin \angle XYZ}{19} =\frac{sin 62}{24} \\sin \angle XYZ=\frac{19}{24} \times sin 62\\\angle ~XYZ=sin^{-1}(\frac{19}{24} \times ~sin~62) \approx 44.35^\circ$

Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.

---------------------------

2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as $35 \times 365 = 12775$ .
Thus, a total of 511000 cigarettes, as $40 \times 12775 = 511000$ .
Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as $15 \times 511000 = 7665000$

One year has 525600 minutes, thus the person loses 14 years of life, as $\frac{7665000}{525600} = 14.5833333$

Looking at the decimal part, the person loses 212 days of life, as $0.5833333 \times 365 = 212.916666655$
Again looking at the decimal part, 22 hours, as $0.916666655 \times 24 = 22$
