Answer:

From the General Equation of a straight line

Y=Mx + c

where M = Slope of the line

c= Intercept on Y axis

y=-4.2x-80

Comparing with the Eqn of a straight line

Slope = -4.2

From the Options the answers are in Fractions

You can easily convert this figure to fraction by Moving the decimal to the back once and then divide by 10

Then we have -42/10

Reducing Further

Answer:

C. -x-6>-3.5

Step-by-step explanation:

One is asked to find which inequality has (x=-3) in its solution set. Remember that an inequality is another way to represent a set of solutions. In essence, it states that all numbers less than; less than or equal to; greater than; or greater than or equal to, are a part of the solution. One simplifies an inequality in a similar manner to how one simplifies an equation, by using inverse operations and simplification. Just note that when multiplying or dividing the inequality by a negative number, one has to flip the inequality sign to ensure the expression remains true.

Simplify each of the inequalities, then evaluate to see which one has (x=-3) as a part of its solution set.

A. -x -6

-x

x>-2.5

B. -x-6>3.5

-x>9.5

x

C. -x-6>-3.5

-x>2.5

x

D. x-6>-3.5

x>2.5

As can be seen, option (C -x-6>-3.5) is the only one that fits this requirement. Since option (C) simplifies down to (x) or in words, (x) is less than (-2.5). This option is the only one that fits the solution since (-3) is less than (-2.5).
