Choose the equation that represents a line that passes through points (−3, 2) and (2, 1).

Step-by-step explanation:

The given line passes through points (−3, 2) and (2, 1).

We use the formula to find the slope of this line.

We use the point slope formula:

We expand to get:

The slope intercept form of the line is:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
