SOLUTION: write and equation of the line containing the points (3,-1) and is parallel to 8x-7y=9

Question 430695: write and equation of the line containing the points (3,-1) and is parallel to 8x-7y=9

8 x -7 y = 9
Find the slope of this line

-7 y = -8 x + 9 1.14
Divide by -7
y = 1.14 x + -1.29
Compare this equation with y=mx+b
slope m = 1.14

The slope of a line parallel to the above line will be the same

The slope of the required line will be 1.14
m=1.14 ,point (3,-1)
Find b by plugging the values of m & the point in
y=mx+b
-1=3.43 +b
b=-4.43
m=1.14
Plug value of the slope and b
The required equation is y=1.14x-4.43,point (-1, 2) and is parallel to the line with equation 8x-7y=9
