Question

What is the equation of the line that passes through the points{1/2,-1/3} and {2,2/3}

A. y=2/3x
B. y=2/3x-2/3
C. y.3/2x+2/3
D. 1/5x+1/4

Answer 1

equation of aline is y=mx+c
just substitute for the values of x then get Y the equation that satisfies both values is the correct one.

Answer 2

like for{2,2/3} for B
x=2, now y=2x/3-2/3
when you substitute for x you will get y=2/3 hence B correct

Answer 3

Wait..

Use tow point slope form:

\[\frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1}\]

Answer 4

*two.
