Question

Consider the line that passes through the points (-5, 9) and (-2, 0). Below are two different equations. Identify the true statement concerning both equations.


Equation #1 Equation #2
y - 9 = -1/3(x + 5) y - 9 = -3(x + 5)

Only equation #1 represents the line that passes through the two given points.

Only equation #2 represents the line that passes through the two given points.

Both equation #1 and equation #2 represent the line that passes through the two given points.

Neither equation #1 nor equation #2 represents the line that passes through the two given points.

Answer 1

slope of the line = 0-9 / -2-(-5) = -9/3
and the line passes through (-5,9)

plug theses values into the general equation

y - y1 = m(x - x1)

where m = slope and x1 = -5 and y1 = 9

Answer 2

so a ?

Answer 3

the slope = m = -9/3 = -3 right?
so how can it be a?

Answer 4

Only equation #2 represents the line that passes through the two given points

Answer 5

yes
