Answer:

When answering this, you need to look at the equation. It has a Y-intercept of 3. Just by seeing that, you can tell the last graph is the right answer.

Step-by-step explanation

Y-intercept is +3 which means it the line crosses the y axis at positive 3.

Step-by-step explanation:

Line is passing through the points:

$(-2,\:3)=(x_1,\:y_1) \:\&\: (2,\:5)=(x_2 ,\:y_2)$

Equation of line in two point form is given as:

$\frac{y -y_1 }{y_1 -y_2 } = \frac{x -x_1 }{x_1 -x_2 } \\ \\ \therefore \frac{y -3}{ 3 -5} = \frac{x -(-2) }{-2 -2} \\ \\ \therefore \frac{y -3}{ - 2} = \frac{x -(-2) }{-4} \\ \\ \therefore \frac{y - 3}{1} = \frac{x +2}{2} \\ \\ \therefore \: y-3= \frac{x}{2} + \frac{2}{2} \\ \\\therefore \: y= \frac{x}{2} + 1 +3\\ \\ \huge \red{ \boxed{\therefore \: y= \frac{1}{2} \:x+ 4}}\\ is \: the \: required \: equation \: of \: line.$

Katena32 [7]

By this equation y = 1,716 - 112x he find that how much money he still owes after each month of the plan.

According to the statement

Jonathan bought a new computer for $1,716

He will pay $143 a month for 12 months.

Total amount he will for 12 months is 143(`12)

Now,

y = the money he still owes

x = the number of months (from x = 0 to x = 12)

y = 1,716 - 112x

So, By this equation y = 1,716 - 112x he find that how much money he still owes after each month of the plan.
