Answer:

y = -4/3x - 1

Step-by-step explanation:

Points on the graph: (0, -1) and (3, -5)

Slope:

m=(y2-y1)/(x2-x1)

m=( -5+1)/(3-0)

m=(-4)/3

m= -4/3

Slope-intercept:

y - y1 = m(x - x1)

y + 1 = -4/3(x - 0)

y + 1 = -4/3x

y = -4/3x - 1

Y = 7x-3<br> Rearrange the equation to make x the subject

EleoNora [17]

Step-by-step explanation:

y = 7x - 3

To make x the subject, you need to isolate it. (Get x by itself)

y = 7x - 3

Add 3 on both sides...

y + 3 = 7x

Divide by 7 (Maybe your teacher wants 7x = y = 3 but if she doesn't and wants x completely by itself here's the answer)

x = y/7 + 3/6

To find how much bags of lettuce there would be, multiply 3.5 times 4.

3.5 x 4 = 14

There are 14 bags of lettuce in the cooler.

Answer:

$\fbox{\begin{minipage}{16em}Option D: y = (4/7)x + 8 is correct\end{minipage}}$

Step-by-step explanation:

(1) A typical form of equation of a line is:

$y = Mx + b$

with, $M$ is slope and $b$ is y-intercept.

(2) Another straight line has equation in form of:

$y = Nx + c$

with $N$ is slope and $c$ is y-intercept

(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:

$M$ x $N$ = -1

(4) Transform the given equation of original line into typical form:

$7x + 4y = -24\\$

<=> $4y = -7x - 24$

<=> $y = (\frac{-7}{4})x - \frac{24}{4}$

<=> $y = (\frac{-7}{4})x - 6$

=> $M = \frac{-7}{4}$

=> $N = \frac{-1}{M} = \frac{-1}{\frac{-7}{4} } = \frac{-4}{-7} = \frac{4}{7}$

=> Option D: $y = (\frac{4}{7})x + 8$ is correct (Slope = $\frac{4}{7}$ )

Hope this helps!
