Pls help asap Consider the following pair of equations:

y = 3x + 3

y = x − 1

Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

Step-by-step explanation:

From the second equation, we can plug in x-1 for y into the first equation. It goes as follows: x-1=3x+3

Now we solve for x by adding 1 to both sides, and then subtracting 3x from both sides to get -2x=4

Thus, x=-2.

Now plug that in for y=x-1 and you get -2-1=-3

So, y=-3

To check, let's plug in the pair. -3=3(-2)+3    -3=-3

-3=-2-1

So, the ordered pair is (-2,-3)

(-2, -3)

Step-by-step explanation:

We are given y = 3x + 3 and y = x - 1.

We can substitute y = x + 1 into the y value for y = 3x + 3, so

x - 1 = 3x + 3  Now, we just subtract x from both sides.

-1 = 2x + 3  We subtract 3 from both sides.

-4 = 2x

2x = -4  We divide both sides by 2

x = -2  Now we have our x value - (-2, y)

Let's substitute the x value into both of the equations given.

1st equation:

y = 3(-2) + 3

y = -6 + 3

y = -3

2nd equation:

y = (-2) - 1

y = -3

We now know that both equations give us the same y value when x = -2 is substituted, therefore our solution is:

(-2, -3)

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
