Answer:
the "b" term is the term "-5 x" in the final quadratic expression
Step-by-step explanation:
Normally the "b" is the "linear term" in a quadratic equation.
So, perform the product of binomials and combine like terms to identify the final "b" term of the quadratic expression you get:
Therefore the "b" term is the term "-5 x" in the final quadratic expression.
Answer:
slope = 2 and y- intercept = 4
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2,0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line
m = =
= 2
The y- intercept is the value of the y- coordinate where the line crosses the y- axis, that is
y- intercept = 4 or (0, 4) in coordinate form, thus
y = 2x + 4 ← equation in slope- intercept form
