Answer:
not 100% but I think it's Step 1
Answer:
y =
x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, 1)
m =
= 
Note the line crosses the y- axis at (0, 1) ⇒ c = 1
y =
x + 1 ← equation of line
The equation is:
2/3n + 4 = 7
Answer:
y=2x-A
Step-by-step explanation:

Since the above polynomial is of degree 7, 7 roots exist.
If the degree is odd and the polynomial coefficients are real, there will be at least one real root, since complex roots come in conjugates.
For the given problem, there is exactly one real root. All the rest are complex.</span>
