Write an equation in slope-intercept form of the line passing through (0, 3) and (2, -1).

zheka24 [161]

Hi there!

»»————-　★　————-««

I believe your answer is:

$y = -2x + 3$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Slope-Intercept Form Is:}}\\\\y=mx + b\\---------------\\\boxed{\text{Key:}}\\\\m - slope\\b - y-intercept\\---------------\\\boxed{\text{\underline{Known Information:}}}\\\\\rightarrow \text{We are given the points: } (0,3) \text{ and } (2, -1)\\---------------\\\boxed$

$\boxed{\text{\underline{Y-Intercept:}}}\\\\\rightarrow \text{Since the line passes at point (0, 3), the y-intercept would be 3.}\\---------------\\\boxed{\text{\underline{Slope:}}}\\\\\rightarrow m =\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1} \\\\\rightarrow m = \frac{-1-3}{2-0}=\frac{-4}{2}=\boxed{-2}\\\\\text{The slope is: } \boxed{-2}\\---------------$

$\boxed{\text{\underline{Equation:}}}\\\\\text{Our equation should be:}\\\\y = -2x + 3$

Math help please with 4 questions :) tysm. will reward. <3

The answer is D. A straight line equals 180°, so when you subtract 180°( your straight line) and the angle it gives you (52°) you get 128°. 180°-52° = 128°

barbara and jeff ate out for dinner the total came to &15.00. they left a 15% tip how much was the tip and the meal together

JulijaS [17]

Answer:

$17.25

Step-by-step explanation:

The tip is 15% of $15.00, or 0.15 * 15 = $2.25

We add that to the meal's cost, which is $15.00

15.00 + 2.25 = 17.25

Rachel hikes at a steady rate from a ranger station to a campground that is 20 mi away. After 2 h, she is 13 mi from the campgro

Angelina_Jolie [31]

Answer:

-3.5

The distance Rachel covers per hour is 3.5 miles

Step-by-step explanation:

After 2 hours, she is 13 miles from the campground.

After 4 hours, she is 6 miles from the campground.

Let x be the number of hours, y be the number of miles from the campground, then we have two points (2,13) and (4,6).

The equation of the line passing through the points $(x_1,y_1)$ and $(x_2,y_2)$ is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Substitute:

$x_1=2\\ \\y_1=13\\ \\x_2=4\\ \\y_2=6$

Hence,

$y-13=\dfrac{6-13}{4-2}(x-2)\\ \\y-13=-3.5(x-2)\\ \\y=-3.5x+7+13\\ \\y=-3.5x+20$

The slope of the line is $-3.5$ and it represents that the distance Rachel covers per hour is 3.5 miles.

Tim tracked the change in outside temperature one afternoon. He recorded a temperature of 85.4 F at noon. The temperature then r

Trava [24]

From 4pm to 5pm the temperature dropped 11.55 degrees

noon 85.4 + 3.85 = 89.25
1st hr 89.25 + 3.85 = 93.1
2nd hr 93.1 + 3.85 = 96.95
3rd hr 96.95 + 3.85 = 100.8
4th hr 100.8 ??
5 pm 89.25

100.8-89.25= 11.55
