Question 98453: These 3 problems do not come from a book but I really need help with them!
If you can solve them as soon as possible, I would greatly appreciate it.
Here they are:
#1:
Write the equation of the line passing through the points listed below. Write the final answer in the slope-intercept form y = mx + b. If the slope (m) or the y-intercept (b) are not integers, fractions must be used.
(-1, 8); (9, 2)

#2:
A line passes through the origin and the point (-6, 4).
Write the equation of the line that passes through (-6, 4) and is perpendicular to the given line.
Write the final answer in the slope-intercept form y = mx + b.
(The slope and y-intercept must be written as fractions, when needed).

#3:
Write the equation for the line perpendicular to
2x - 5y = 5 and passes through the point (-2, -5).
Enter the variable expression Ax + By separately from the constant term C.
Your response should be given in standard form where A, B and C are the smallest possible integers and A > 0.
Thanks so much.
