What is the Y-INTERCEPT of the line y = 3x - 5

Answers

Answer:

(0,-5)

Step-by-step explanation:

In y = mx+b, b is the y-value of the y-intercept.

Here, b = -5.

Note: the y-intercept is a POINT, not a value.

Step-by-step explanation:

Hey there!

Given equation is; y= 3x-5.

Comparing the equation with y= mx+b, where "b" is y-intercept. we get;

y-intercept= -5

Therefore, y-intercept of the equation is"-5".

GIVING BRAINLIEST easy question
A bridge is 10 m above a railroad track and at right angles to it. A train is running at the rate of 20 m/s passes under the center of the bridge at the same instant that a car running 15 m/s reaches that point. How rapidly are they separating 3 seconds later?

Answers

Taking the point directly under the center of the bridge as the origin,
x = 20t, y = 15t, z = 10
let s be thedistance between them at time t,
s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100
2s ds/dt = 1250t
ds/dt = 625t/s

when t = 3, s = √(625*9+100) = 75.6637
ds/dt = 625*3/75.6637 = 24.78 m/s

The time taken that should be rapidly are distinct 3 seconds later should be considered as 24.78 m/s.

Calculation of the time taken:

Here the point should be considered directly under the center of the bridge as the origin

Here

x = 20t, y = 15t, z = 10

let us assume s be the distance between them at time t,

So it be like

[tex]s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100[/tex]

2s ds/dt = 1250t

ds/dt = 625t/s

Now at the time when

t = 3,

[tex]s = \sqrt (625*9+100)[/tex] = 75.6637

So,

ds/dt = [tex]625*3/75.6637[/tex] = 24.78 m/s

How can knowing the slope and y-intercept help you graph an equation?​

Answers

Answer:

To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.There are two important things that can help you graph an equation, slope and y-intercept.SlopeWe're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.

Write an equation in the form y=Mx+b to model the given representation

Answer:

y= 20x +30

Step-by-step explanation:

y - intercept of the graph is 30

Slope of the graph is [tex]\frac{20}{1}[/tex]

Answer:

y = 20x + 30

Step-by-step explanation:

y=mx+b

b value = y-intercept, so you find where the line crosses the y-axis.

Find point at (0,30); b = 30

m value = rise/run (rise over run) (y/x)

find the next point that the graph intersects at and count add to it to find 30.

the closest point is at (-1,10)

go back to rise/run

30-10 = 20

0-(-1) = 1

20/1 =20 is your m value

plug m value and b value into equation to form your line.

y=20x+30
