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.

Slope of perpendicular lines : 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 $y=-x+10$

y-intercept :

Substitute $x=10$

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

PLEASE HELP ASAP 50 POINTS AND BRAINLYEST

Ludmilka [50]

Answer:

Either x = 3, y = 2

(3,2) is your answer.

Step-by-step explanation:

2x +y = 8 (1)

y = - x+ 5 (2)

Put equation (2) into equation (1). Use the y value in (2) to go into the y value in (1).

2x - x+5 = 8 Combine the x values

x + 5 = 8 Subtract 5 from both sides

x + 5-5 = 8-5

x=3

Now go back to (2). Put x in for the value of -x. Watch the sign.

y = -3+ 5

y = 2

So the answer is (3,2)
