Equation of the horizontal line through  (7 , -5)

Horizontal line is a slope of 0, so y=constant.

Answer: y = -5

Slope -2  through (-4 , -5)

Point slope form of line slope m thru (a,b) is y-b = m(x-a)

y - -5 = -2 (x - -4)

y + 5 = -2x - 8

Answer: y = -2x - 13

check: slope is right, -2(-4) - 13 = 8 - 13 = -5, good

Explain how you would graph the following set of parametric equations by plotting points and describing the orientation.
lyudmila [28]
Concept:

First eliminate the t from x=3t and then put it in y=t² and then graph it. As, limit of t is not  restricted so t ∈ R(all real numbers)

As it is difficult to make graph here so I have solved it by hand and add all detail regarding it.

Kelvin says that 22/30 is greater than 22/32 do you agree ? explain
kozerog [31]
When two fractions have the same numerators, the one with the smaller denominator is the greater fraction.

30 < 32 \Rightarrow \frac{22}{30} > \frac{22}{32}

So Kelvin is right.
