Answer:

y=\frac{-5}{4}x+5

Step-by-step explanation:

Slope intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Find the slope of the line (</u>m<u>)</u>

To do this, we can plug the two given points (0,5) and (4,0) into the slope equation:

\frac{y_2-y_1}{x_2-x_1} \\= \frac{0-5}{4-0}\\= \frac{-5}{4}

Therefore, the slope of the line is \frac{-5}{4}.

<u>2) Find the y-intercept of the line (</u>b<u>)</u>

Recall that the y-intercept is the value of y when the line crosses the y-axis. We don't actually need to perform any calculations because on the graph, we can see that the line crosses the y-axis when y=5.

Therefore, the y-intercept of the line is 5.

Plugging both m and b into y=mx+b, we have a final equation of:

y=\frac{-5}{4}x+5

I hope this helps!

When I double my number, subtract three, subtract my number, and add four, I get my number plus two. What is my number?
marishachu [46]

Answer:

Any real number

Step-by-step explanation:

Let your no.= x

double the number=2x

add 4 = 2x+4

subtract same number=2x+4-x

subtract 3=2x+4-x-3

get number plus 1=x+1

 

so equation we get

2x+4-x-3=x+1

x+1=x+1

 

x=x

 

it means  x is equal to all real number

So your number can be any real number

What is the slope of the line given by the equation y=-1/3x? Entee your answer as an integer or fraction in lowest terms.
Serhud [2]
-1/3

really? it's that easy dude. 

whatever number is next to x, like say, 3x, that number would be the slope, so it would be 3.

hope it helped.
