In proportional, it is y/x=k or y=kx
basically it is like y=mx+b, it is a line

the complete question is

Which phrase best describes the graph of a proportional relationship?

A.a straight line passing through the origin

B.a straight line

C.a curve

D.not a straight line

we know that

A relationship between two variables, x, and y, represent a proportional relationship (direct variation) if it can be expressed in the form

$\frac{y}{x}=k\\ or\\ y=kx$

the equation $y=kx$ is a straight line passing through the origin with slope equal to k

therefore

the answer is the option

A.a straight line passing through the origin

Factor completely x3 + 4x2 + 8x + 32. (x + 4)(x2 + 8) (x − 4)(x2 − 8) (x − 4)(x2 + 8) (x + 4)(x2 − 8)

icang [17]

$\tt x^3+4x^2+8x+32\\\\=x^2(x+4)+8(x+4)\\\\=\boxed{\tt(x+4)(x^2+8)}$

Simplify the slope of AC

Lemur [1.5K]

Answer:

$Slope\:\: \overline{AC} =1$

Step-by-step explanation:

A is on the same point on the x-axis as B and the same point on the y-axis as D

Therefore, the coordinate of A is (0,0)

C is on the same point on the x-axis as D and the same point on the y-axis as B.

Therefore, the coordinate of C is (a,a)

We are to determine the slope of the line joining A to C.

$Slope, m =\dfrac{y_2-y_1}{x_2-x_1} \\(x_1,y_1)=(0,0),(x_2,y_2)=(a,a)\\$Therefore, Slope of AC$\\m =\dfrac{a-0}{a-0}\\=\dfrac{a}{a}\\\\=1$

$Slope\:\: \overline{AC} =1$
