Question 454798: Write an equation of the line containing the given point and parallel to the given line. Express youra nswer in the form y=mx+b.
(8,9); x +8y = 9
The equation of th eline is y=________
Would I begin by subtracting 8y from both sides an then divide 9 by both sides?

a parallel line means the slope is the same, so the x and y coefficients don't change

the term that changes is the constant (the 9) which determines the intercept (where the line crosses the axis)

substitute the point into the equation to find the new constant term ___ (8) + 8(9) = ?

then solve the new equation for y to get the slope-intercept form (y = mx + b)
