Question

Consider the line that passes through the points (4, -3) and (2, -1). Below are two different equations. Identify the true statement concerning both equations.
Equation #1 Equation #2
y – 3 = –1(x + 4) y – 1 = –1(x + 2)

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

g-f=-5

Answer 2

what ??

Answer 3

can you explain ?

Answer 4

You need to determine if the points are both solutions to each equation. If both points solve the equation, then the line passes through the points.

Answer 5

Do you know how to determine if the points are solutions to the equations?

Answer 6

no .

Answer 7

Replace the 'x' and 'y' terms in the equations with the coordinate pair. If the equation is true (the left side equals the right side) then the coordinate pair is a solution.
