The line above goes through points (-4,0) and (0,1). what is the equation of the line?
1 answer:
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

Answer:
The rational zero of the polynomial are .
Step-by-step explanation:
Given polynomial as :
f(x) = 4 x³ - 8 x² - 19 x - 7
Now the ration zero can be find as
,
where P is the constant term
And Q is the coefficient of the highest polynomial
So, From given polynomial , P = -7 , Q = 4
Now ,
I.e =
Or, The rational zero are
Hence The rational zero of the polynomial are . Answer
