Hello i need help on number 1,2,3,4,5 and 6.

A. m = -1

b = 1

Equation: y =-1x+1

B. m = 2

b = -3

Equation: y = 2x-3

Step-by-step explanation:

m = slope (rise/run)

b = y-intercept (where the line crosses the y-axis)

Line A:

Slope = -1

Y-intercept = 1

Equation: y = -1x+1

Line B:

Slope = 2/1

Y-intercept = -3

Equation: y = 2x-3

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

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.
