slope intercept equation from graph

Answers

The equation for your problem is y= 2x + 4. Reason is it goes up 2 and right 1. The y- intercept is 4 on the y - axis

Answer:

y = 2x+4

Step-by-step explanation:

Hi there,

In this linear graph, we notice that the slope is 2 since the [tex]\frac{rise}{run}[/tex] is [tex]\frac{2}{1}[/tex]. We also notice that this line crosses the y-axis at x = 0. Based on the information we found, we can put it in the linear equation y = mx+b.

Here is what the m and b means for reference:

m = slope

b = y-intercept

The final answer will be y = 2x + 4.

Hope this answer helps clarify this concept. Feel free to ask me questions. Cheers.

On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?

Answers

Answer:

30 first-class tickets were sold and 260 coach tickets were sold.

Step-by-step explanation:

Let a first-class ticket be represented by f and let a coach ticket be represented by c.

On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

[tex]f+c=290[/tex]

The total income was $95,280. Therefore:

[tex]680f+288c=95280[/tex]

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

[tex]85f+36c=11910[/tex]

From the first equation, we can subtract f from both sides:

[tex]c=290-f[/tex]

Substitute:

[tex]85f+36(290-f)=11910[/tex]

Distribute:

[tex]85f+10440-36f=11910[/tex]

Simplify:

[tex]49f=1470[/tex]

So:

[tex]f=30[/tex]

From the previous equation:

[tex]c=290-f[/tex]

Substitute:

[tex]c=290-30=260[/tex]

30 first-class tickets were sold and 260 coach tickets were sold.
