Q:
# Which set of points includes all of the solutions for y = negative four fifths times x plus two?line going through 0 comma 2 and 5 comma negative 2 (15, 10), (0, 2), and (−10, 10) (−10, 10), (−5, 6), (0, 2), (5, −2), (10, −6) (x, y) for all real numbers (x, negative four fifths times x plus two) for all real numbers

Accepted Solution

A:

Answer:d) [tex](x, -\frac{4}{5}x+2)[/tex] for all Real NumbersStep-by-step explanation:The given equation is:[tex]y=-\frac{4}{5}x+2[/tex]We have to find which of the given options list all of the possible solutions for the given equation. i.e. we have to find the option which lists all the points that satisfy the given equation.Since, there is no restriction on x and y, this gives us a hint that there are an infinite number of values that would satisfy this equation. So this eliminates the first two options.Since, the given equation is not an identity, it will not hold true for each and every real value of x. Although, the number of solutions are infinite but it does not include each and every real number. So this eliminates option c as well.This leaves us with option d.The first coordinate of the ordered pair is x and the second coordinate is the equation defined for y. i.e. the ordered pair is:[tex](x, -\frac{4}{5}x+2)[/tex] For all real values of x.For every value of x, the ordered pair obtained will satisfy the given equation as the ordered pair is derived from the original equation. So, this option includes all the solutions for the given equation.
