Write the equation of the line in fully simplified slope-intercept form.
Julli [10]

Answer:

y = -x + 2

Step-by-step explanation:

[slope-intercept form] y = mx + b

m [slope] = ∆y/∆x = y₂–y₁ / x₂–x₁

b [y-intercept] = (0,b) → x = 0.

If y = 2 when x = 0, b = 2.

Since y decreases by 1 unit everytime x increases by 1 unit

a decrease by 1 unit is represented by -1, and an increase of 1 is represented by 1.

So a decrease of -1 over an increase of 1

is -1/1 = -1 = m.

kicyunya [14]

Answer:

The correct option is First. i.e <u>consistent.</u>

The System shown is <u>consistent.</u>

Step-by-step explanation:

Consistent:

A consistent system of equations is a system that has at least one solution.

Our System in graph has only and only ONE solution that is on X-axis

Where the lines are intersecting each other.

Hence, The System shown is <u>consistent.</u>

Inconsistent:

An inconsistent system of equations is a system that has no solution.

Equivalent:

Systems of equations that have the same solution are called equivalent systems. Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.
