What equation represents the line that passes through the points (-3 7 and (3 3?

dexar [7]

Hello : let A(-3,7) B(3,3)
the slope is : (YB - YA)/(XB -XA)
(3-7)/(3+3) = -2/3
an equation is : y=ax+b a is a slope

y = (-2/3)x +b

the line through point B (3,3) : 3 = (-2/3)(3)+b
b =5
the equation is : y =(-2/3)x+5

What is the sale price of $160 airpods with an 18% discount?

Ahat [919]

Answer:

$131.20

Step-by-step explanation:

$160 is the full price, so it is 100% of the full price.

With a discount of 18%, you pay 100% - 18% = 82% of the full price.

82% of $160 =

= 0.82 * $160

= $131.20

Answer: $131.20

a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is

ANTONII [103]

Answer:

$(y-30)=2(x-10)$

Step-by-step explanation:

We have been given that a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is 50 centimeters tall.

First of all we will find slope of our line using given points.

$m=\frac{y_2-y_1}{x_2-x_1}$

Upon substituting coordinates of our given points in slope formula we will get,

$m=\frac{50-30}{20-10}$

$m=\frac{20}{10}=2$

Therefore, slope of our given line is 2.

Since the equation of a line in point slope form is $(y-y_1)=m(x-x_1)$ .

Upon substituting m=2 and coordinates of one point in above equation we will get,

$(y-30)=2(x-10)$

Therefore, the equation that models the height of the plant (y) after x days will be $(y-30)=2(x-10)$ .
