Which equation represents a line that passes through (–9, –3) and has a slope of –6?
Xelga [282]

Answer:

The required equation of line is y=-6x-57.

Step-by-step explanation:

The point slope form of a line is

y-y_1=m(x-x_1)

Where m is slope of the line.

It is given that a line that passes through (–9, –3) and has a slope of –6.

Substitute m=-6, x₁=-9 and y₁=-3 in the above equation.

y-(-3)=-6(x-(-9))

y+3=-6x-54

Subtract 3 from both the sides.

y=-6x-54-3

y=-6x-57

Therefore the required equation of line is y=-6x-57.

lisabon 2012 [21]

answer:

measure of angle 1 is 130°.

step by step:

angle 8 = 50

angle 6 = 50 (because of vertical angles)

angle 4 = 50 (because fo alternate interior angles)

therefore, angle 1 = 130 (because of linear pairs)

angle 1 and angle 4 add up to 180°

Simplify 2a^2b^3 (4a^2 + 3ab^2 - ab) =?
stellarik [79]

The correct answer is D.D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4

You can tell this by the lead term alone. When you mutliply the term outside to the lead term, D is the only one that has that term.

2a^2b^3*4a^2 = 8a^4b^3

D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
