(04.04) which of the following has a graph that is a straight line? (4 points) equation 1: y = 4x3 + 6 equation 2: y = 5x − 4.5 equation 3: y2 = x − 1 equation 4: y = 2x2 + 6

Step-by-step explanation:

Given equations :

Equation 1:

Equation 2: y = 5x − 4.5

Equation 3:

Equation 4: .

First equation has degree 3 because power of x is 3.

Second equation has degree 1 because power of x is 1.

Third equation as power of y as 2.

And fourth equation as power of x as 2.

Note: An equation with power of x and y or any variable only 1 to be graph be a straight line.

Only second equation has power of x and y is 1.
