Anyone know this? plz help..

Marsha earns the most money per item sold because her line increases at a faster rate than Dreya's.

Step-by-step explanation:

The slope of the line is correlated to the amount of money sold. Because Marsha's line's slope is higher than Dreya's, she earns more.

C

Step-by-step explanation:

I'm pretty sure it's C because 400/3 = 133.33 and 600/3 = 200 so I'm assuming it's close to that. Also Dreya's line starts higher than Marsha's.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

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

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
