Question

(4,7);2x+y=3

Answer 1

is there a question? like perhaps "is this point on the line?"

Answer 2

write an equation of the line containing a given point and perpendicular to the given line.

Answer 3

ok now that is a question

Answer 4

the slope of
\[2x+y=3\] is -2. so the slope of the perpendicular line is
\[\frac{1}{2}\] then use the point slope formula
\[y-y_1=m(x-x_1)\] with
\[m=\frac{1}{2},x_1=4,y_1=7\]
