Every proportional relationship is an equation like y = a number times 'x'. When you graph that equation it's a straight line that goes through the origin and every point on the line satisfies the equation. Line B is the only graph that looks like that. The others all have a piece of a proportional relationship. Their bottom pieces are proportional relationships but then they break and the top pieces are not.

Which of the following is a point-slope equation of a line that passes through

RSB [31]

Please, check the options of the question. The point-slope equation needs the slope, m, in the equation.

Answer:

The point-slope equation of the points (5,2) and (-1,-6) is

$\\ y - 2 = \frac{4}{3}(x-5)$ or,

$\\ y + 6 = \frac{4}{3}(x+1)$

which are the same as

$\\ 3y-4x+14 = 0$ , (which is not a point-slope equation, though)

Step-by-step explanation:

The point-slope equation is given by:

$\\ y - y_{1} = m(x - x_{1})$

Where m is the slope of the line:

$\\ m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Having the points (5,2) and (-1,-6), then

$\\ m = \frac{-6 - 2}{-1 -5}$

$\\ m = \frac{-8}{-6}$

$\\ m = \frac{4}{3}$

Then, the point-slope equation of the points (5,2) and (-1,-6) is

$\\ y - 2 = \frac{4}{3}(x-5)$ or

$\\ y + 6 = \frac{4}{3}(x+1)$

The below graph represents both lines (they are the same line).

Vladimir79 [104]

Hey there,

Your question states: A customer went to a garden shop and bought some potting soil for $11.50 and 9 shrubs. The total bill was $94.75. Write and solve an equation to find the price of each shrub.

So, I will do 94.75 minus 11.50 because he bought nice scrubs so that would be 83.25.

I will do 83.25 divided by 9 because that's the number that person bought, each scrub will end up to be 9.25.

Hope this helps.
