Answer:

y = 9x - 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, - 38) and (x₂, y₂ ) = (8, 61)

m = \frac{61+38}{8+3} = \frac{99}{11} = 9, thus

y = 9x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, 61), then

61 = 72 + c ⇒ c = 61 - 72 = - 11

y = 9x - 11 ← equation of lie

What are 2 points on the graph for 6x-5y=25
zepelin [54]
To find any two random point on the graph of 6x-5y=25, we can just plug in any two values for x and solve for y, and find the 2 points in the form of (x,y).

So lets plug in x=0.

\sf 6x-5y=25
\sf 6(0)-5y=25
\sf -5y=25
\sf y=-5
So one point is (0,-5)

And to find another point, we can plug in x=1

\sf 6x-5y=25
\sf 6(1)-5y=25
\sf 6-5y=25
\sf -5y=25-6
\sf -5y=19
\sf y=19/-5
\sf y=-3.8
So another point is (1,-3.8)

Use the Distributive Property to simplify the following expression. a: 4(x+2) b; -5(9+x) c: 7(x-3)
ExtremeBDS [4]
<h3>hello!</h3>

=======================================================

The Distributive Property states the following:-

\longrightarrow\sf{a(b+c)=ab+ac

Where

\longrightarrow\sf{a,~b,~and~c~can~be~either~constants~or~variables}

Now, let's use this property to simplify our expressions.

The first one is

\bigstar{\underline{\boxed{{4(x+2)}}}

Simplify by distributing 4:-

\longrightarrow\sf{4~times~x~+4~times~2}

Add the products:-

\longrightarrow\sf{4x+8}

\rule{250}{2}

Solve the next one:-

\bigstar{\underline{\boxed{\sf{-5(9+x)}}}

Distribute -5 & add the products:-

\longrightarrow\sf{-45-5x}

\rule{250}{2}

Solve the last one:-

\bigstar{\underline{\boxed{7(x-3)}}

Distribute 7:-

\longrightarrow\sf{7x-21}

======================================================

<h3>note:-</h3>

Hope everything is clear; if you need any more explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)
