(-3,y), (-9,-2); m=1

Answer:

The value of y is 4

The equation of line is y = x + 7   .

Step-by-step explanation:

Given as :

The points are

(x_1, y_1) = (- 3, y)

(x_2, y_2) = (- 9, -2)

The slope = m = 1

Now,<u> The slope is calculated in points form</u>

So, Slope = \dfrac{y_2-y_1}{x_2-x_1}

I.e m = \dfrac{y_2-y_1}{x_2-x_1}

or, 1 = \dfrac{- 2 - y}{- 9- (-3)}

or, 1 = \dfrac{- 2 - y}{- 6}

or, 1 × (-6) = - 2 - y

or, - 6 = - 2- y

or, y = - 2 + 6

∴ y = 4

So, The new points as

(x_1, y_1) = (- 3, 4 )

(x_2, y_2) = (- 9, -2)

<u>So, the equation of line in slope - point form can be written as</u>

y - y_1 = m ( x - x_1 )

i.e y - 4 = ( 1 ) × ( x - (-3) )

or, y - 4 = x + 3

∴ y = x + 3 + 4

Or, y = x + 7

So, The equation of line is y = x + 7

Hence The value of y is 4

And The equation of line is y = x + 7   . Answer

A parking garage charges a $2.50 daily fee plus an hourly rate of $4.00. If you have $12.50 to pay for parking, how long can you
Vesnalui [34]

Step-by-step explanation:

First we need to set up an equation so

12.50=4x+2.50

Simplify each side by subtracting the initial fee of 2.50

10=4x

divide by 4 to isolate x

2.5=x

You can park for 2.5 hours with your budget

balandron [24]
">" means results into or you can think about it as saying equals (=)
√75 = √5 * √15 > √5 * √5 * √3 > 5<span>√3
</span><span>√3
</span>√75 = √5 * √15 > √5 * √5 * √3 > 5√3
√3
Which then leads to..
5√3 + 5√3 + √3 + √3
