The line with equation y= 2x + 3 is reflected in the x-axis. Which of the following is the equation of the new line?

a) y = 2x + 3

b) y = -2x + 3

c) y = 2y + 3

d) y = 1/2 x + 3

e) y = -2x -3

Step-by-step explanation:

When a graph is reflected about the x-axis, their x-intercept(s) are invariant point(s).

For y = 2x + 3, the x-intercept is -3/2.

Also the slope of the line graph when reflected about the x-axis will change from m to -m.

Therefore the new slope is -2.

We have y = -2x + c.

When x = -3/2, y = 0.

=> (0) = -2(-3/2) + c, c = -3.

Hence the answer is y = -2x - 3. (E)

i those same problems in math and dont know how to do them

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
