What is the y-intercept of the equation of the line that is perpendicular to the line y =

Luda [366]

Answer:

$y$ intercept $=10$

line $y=-x+10$

Step-by-step explanation:

Let $y=mx+b$ is the required line.

<u>Slope of perpendicular lines :</u> If $m_{1}$ and $m_{2}$ be slope of two perpendicular lines. Them $m_{1}\times m_{2}=-1$

$y=mx+b$ is perpendicular to $y=x+10$

the slope of $y=x+10$ is $=1$

$m\times 1=-1\\m=-1$

Hence eqn is $y=-x+b$

This equation passes through $(15,-5)$

$-5=-15+b\\b=-5+15\\b=10$

so the line is $y=-x+10$

<u>y-intercept :</u>

Substitute $x=10$

$y=0+10\\y=10$

PLEASE HELP!!!!!! i will give brainiest!

Answer:

$\sf B) \ y=-\dfrac{1}{5}x-4$

Explanation:

Equation: y = mx + b [where "m" is slope, "b" is y-intercept]

The y-intercept (b) is -4

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

Here take two points: (0, -4), (5, -5)

$\sf slope \ (m) : \dfrac{-5-(-4)}{5-0} = -\dfrac{1}{5}$

$\sf Hence \ equation : y = -\dfrac{1}{5} x -4$

Please help if you can!!!!

Answer:Well, I don't know what you got so I can't tell you if it is right.

If it works in both equations, it depends of whether your equations are set up correctly.

Here is how I would do this problem.

Let x = no. of hot dogs,y = number of sodas.

First equation is just about the number of things.

x + y = 15

Second equation is about the cost of things.

1.5 x + .75 y = 18

solve x+y = 15 for y y = 15-x substitute into second equation

1.5x + .75(15 - x) = 18

You should get the correct answer for number of hot dogs if you solve this correctly. Put your answer in the x + y =15 equation to get y. Then put both x and y into the cost equation and check your answer.

Hope this helps.
