MATHEMATICS: Writing the Equation of A Line(2)?

Question

Write the equation of a line in standard form (Ax+By=C) given the following:

a) passing through (-7,5) and parallel to the x-axis

b) passing through (5,-8) and perpendicular to the x-axis


Thank you in advance.

Answer 1

a) y = 5
or
0x + 1y = 5

"Parallel to the x-axis" is "y = "

b) x = 5
or
1x + 0y = 5

"Parallel to the y-axis" (or "perpendicular to the x-axis" which is the same) is "x = "

Answer 2

Normally, Take the equation to be of the form y = mx +c, where
m = slope
c = y-intercept
The following two problems are exceptions to this rule:

a) passing through (-7,5) and parallel to the x-axis
slope , m = 0
so y = 5 is the equation

b) passing through (5,-8) and perpendicular to the x-axis
slope, m = infinity
so x = 5 is the equation

Answer 3

Yowee what a funky first examine of the day, with some reliable solutions. i'm no longer so reliable at math, yet i will attempt. 5' 7" + very almost absolutely everyone here = D seemin like a slice of eco-friendly cheese and a heat, stale beer.
