Identify the solution

Mathematics
1 answer:
sashaice [31]3 years ago

Answer:

(- 1, - 1 )

Step-by-step explanation:

Given the 2 equations

y = 4x + 3 → (1)

x + y = - 2 → (2)

Substitute y = 4x + 3 into (2)

x + 4x + 3 = - 2, that is

5x + 3 = - 2 ( subtract 3 from both sides )

5x = - 5 ( divide both sides by 5 )

x = - 1

Substitute x = - 1 into (1)

y = 4(- 1) + 3 = - 4 + 3 = - 1

Thus x- value is - 1 and y- value is - 1

What is the equation of the following line written in general form? (The y-intercept is -1.)
Strike441 [17]
2x-y-1=0

There are 2 ways that you can solve this . Either plug in the x and y value into each equation until it is right or rewrite the equation .
the equation in slope intercept form is y=2x-1
When you get y by itself in the last one it is also equal to y=2x-1
For both ways work is attached !
