• Write the equation of the line that passes through the points (-7,0) and(-3,-9). Put your answer in fully reduced point-slope

coldgirl [10]

We want to calculate the line that passes through the points (-7,0) and (-3,-9). Recall that the equation of a line is

$y=mx+b$

where m is the slope and b is the y intercept. We can calculate first the slope and then find the value of b. To do so, recall that given points (a,b) and (c,d) the slope of the line that passes through them is given by the formula

$m=\frac{(d\text{ -b)}}{(c\text{ -a)}}=\frac{b\text{ -d}}{a\text{ -c}}$

so by taking a=-7, b=0, c=-3 and d=-9 we get

$m=\frac{0\text{ - (-9)}}{\text{ -7 -( -3)}}=\frac{9}{\text{ -4}}=\text{ -}\frac{9}{4}$

so our equation becomes

$y=\text{ -}\frac{9}{4}x+b$

so know we want this line to pass through the point (-7,0), so whenever x= -7 then y=0 so we have the equation

$0=\text{ -}\frac{9}{4}(\text{ -7)+b}$

or equivalently

$0=\frac{63}{4}+b$

so if we subtract 63/4 on both sides, we get

$b=\text{ -}\frac{63}{4}$

so our equation would be

$y=\text{ -}\frac{9}{4}x\text{ -}\frac{63}{4}$

Anastaziya [24]

Answer:

$C = 1000S + 500B$

Step-by-step explanation:

Given

$S = Banana\ Splits$

$B=Bacon\ Rolls$

Reading through the question, we have:

Number of calories per serving:

$S \to 1000$

$B \to 500$

Let

$x = Cholesterol$

$y =Sugar$

So, we have:

Each serving of S

$x \to 1S$

$y \to 3S$

Each serving of B

$x \to 4B$

$y \to 1B$

Recommendation

$x \to \le 10$ - i.e. not more than 10 units of cholesterol

$y \to \ge 2 \& \le 9$ i.e. At least 2units but not more than 9 units of sugar

So, the constraints are:

$S + 4B \le 10$

$3S + B \ge 2$

$3S + B \le 9$

Recall that the calories per serving is:

$S \to 1000$

$B \to 500$

Hence, the objective function is:

$C = 1000S + 500B$
