Answer:

First, you have to rewrite the question in a way to isolate your Y. This means moving the -3 over to the other side.

Y = 2(x+1) + 3

Now, you should multiply the 2 out in the parenthesis.

Y=2x+2+3

Now, combine like terms! In this case, your like terms are 2 and 3.

Y=2x + 5

Because there are no more like terms, and Y is completely isolated, Y=2x + 5 is your answer!

What is the equation of the line parallel to 3x-y-7=0 that passes through point (-5, -3)

Answer:

The equation of the line in slope-intercept form is y =3x+12

Step-by-step explanation:

The first step is to rewrite the equation of the line in the slope-intercept form in order to identify the slope of the line. The re-written equation is;

y = 3x-7.

This implies that the slope of the line is 3. Since the two lines are parallel they they will have equal slope of 3. The slope-intercept form of the equation of this line will be;

y =3x+c.

Since the line passes through (-5, -3), substitute x with -5 and y with -3 to solve for c;

-3 =3(-5)+c.

We find c =12 and the equation of the line becomes;

y =3x+12.

Answer:

It means that for every 1 unit of time, the equation shows an increase of 8.38 units of distance.

Step-by-step explanation:

Slope is $\frac{rise}{run}$ . Any number that does not have a denominator technically has a denominator of 1. Therefore, your slope is actually $\frac{8.38}{1}$ . That means you have a rise, or the vertical progression, of 8.38 while your run, or your horizontal progression, is 1. For every unit your line travels horizontally, it travels 8.38 units vertically. I hope this makes sense.
