What is the equation of the line that passes through the point (5,6) and has a slope of 2 ?

Mathematics
1 answer:
Serhud [2]3 years ago
4 0

Answer:

y = 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (5, 6) into the partial equation

6 = 10 + c ⇒ c = 6 - 10 = - 4

y = 2x - 4 ← equation of line

PLEASE HELP I WILL MARK YOU BRAINIEST PLEASE
cupoosta [38]

Answer:

Zeniab makes the most money by $0.25, and would make $2.50 more.

Step-by-step explanation:

Okay, the good news is, this problem is about finding how much you make in an hour.

Zainab makes $44 for 8 hours

and

Keziah makes $47.25 in 9 hours.

in each problem, we can set them up in an equation of

$44=8x

and

$47.25=9x

In the first equation, divide both sides by 8 to isolate the x.

that would be 44/8 = x which is $5.50 per hour for Zainab.

In the second equation, divide both sides by 9 to isolate the x.

That would be 47.25/9 = x which is $5.25 per hour for Keziah.

This means that Zainab would make more per hour, and to find the second part of the question for a 10 hour job,

(<u>You can multiply any number by 10 easily by moving each number up one place. Hundreds go to the thousands when you multiply by 10 as an example. In this problem, 5.50 times 10 would be $55.00 because the 5 behind the decimal would be moved up infront of the decimal)</u>

<u>Zainab would make $55 for 10 hours</u>

<u>Keziah would make $52.50 for 10 hours</u>

<u>Then, take the difference of those final totals, which is $2.50, or multiply $0.25 by 10 to get $2.50</u>

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

Therefore,

slope = (-12-(-9))/(-6-(-9))
