Which choice is the equation of a line that passes through (9, -3) and is parallel to the line represented by this equation? y=5/3x-4

Verified Answer :

Answer:

\(y+3=\frac{5}{3}(x-9)\)  or  \(y=\frac{5}{3}x-18\)

Step-by-step explanation:

step 1

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are the same

we have

\(y=\frac{5}{3}x-4\)

therefore

The slope m of the line parallel to the given line is

\(m=\frac{5}{3}\)

step 2

Find the equation of the line in point slope form

\(y-y1=m(x-x1)\)

we have

\(m=\frac{5}{3}\)

\(point\ (9,-3)\)

substitute

\(y+3=\frac{5}{3}(x-9)\) ----> equation of the line in point slope form

step 3

Find the equation of the line in slope intercept form

\(y=mx+b\)

we have

\(y+3=\frac{5}{3}(x-9)\)

Isolate the variable y

\(y+3=\frac{5}{3}x-15\)

\(y=\frac{5}{3}x-15-3\)

\(y=\frac{5}{3}x-18\)
