Answer:

y = 23x - 57  see below

Step-by-step explanation:

You can use the slope intercept equation which is

y = mx + b

where m is the slope of the line and b is the point on the y-axis when x=0 (the y-intercept)

Slope = rise over run

Rise is the difference between the y points

Run is the difference between the x points

If you take two of the coordinates you can get the Rise and Run

Rise = difference between y values    -57 and -34 which is 23

Run = difference between the x values    0 and 1 which is 1

The slope is 23.  If you visualize the line based on the coordinates, you will see that the line slants upward from left to right so the slope must be positive.

m = 23 (slope)

b is where the line crosses the y axis when x=0.  The first set of coordinates gives you that.  ( 0, -57).

b = - 57

The equation should be y = 23x - 57

You can test this by plugging in a couple of the coordinates.

(0, - 57)   y = 23(0) - 57 OR  y = 0 - 57  OR y = - 57

(1, - 24)  y = 23(1) - 57  OR  y = 23 - 57  OR   y = - 24

etc

The ages of 3 brothers are represented by consecutive integers. If the oldest brothers age is decreased by twice the youngest br
zepelin [54]

Answer:

The youngest brother's age is 21 years.

Step-by-step explanation:

Given:

The ages of 3 brothers are consecutive integers.

If the oldest brothers age is decreased by twice the youngest brother age the result is -19

To find the age of the youngest brother.

Solution:

Let the age of youngest broth be = x  years

The ages are consecutive integers.

So, age of the next older brother will be = (x+1) years

The age of the oldest brother will be = (x+2) years

The oldest brothers age is decreased by twice the youngest brother age.

The above statement can be represented as:

⇒ (x+2)-2x

Simplifying.

⇒ x-2x+2

⇒-x+2

The result for the above expression = -19.

So, we have:

-x+2=-19

Subtracting both sides by 2.

-x+2-2=-19-2

-x=-21

Multiplying both sides by -1.

∴ x=21

Thus, the youngest brother's age is 21 years
