Question

Find an equation of the line. Write the equation using function notation. Through (8,-3); parallel to 8x+3y=79

Answer 1

the required line is parallel to 8x+3y=97
so the slopes of the two lines are the same

Answer 2

for the given line
are u can specify the slope?

Answer 3

Do we need to use the y-intercept form?

Answer 4

yes

Answer 5

y=mx+b, (8,3) 8x+3y=79

Answer 6

you have 8x+3y=79
then 3y=-8x+79
and y=-8/3 x+79/3
then by compare this equation with the general one (y=mx+c)
m=-8/3

Answer 7

now you have
m=-8/3
and
a point (8,-3)

Answer 8

use the equation
\[y-y _{1}=m(x-x _{1})\]

Answer 9

got it?

Answer 10

8-3

Answer 11

I'm having a hard time trying figure out the y-y1=m(x-x1)

Answer 12

ok
y+3=-8/3 (x-8)
y+3=-8/3 x+64/3
y=-8/3 x +64/3 -3
y=-8/3 x +55/3
