Question

Write an equation in slope-intercept form of the line through point P(–10, 1) with slope –5.

y = –5x – 49
y – 1 = –5(x + 10)
y – 10 = –5(x + 1)
y = –5x + 1

Answer 1

y – 1 = –5(x + 10)

Answer 2

line through point P(–10, 1) with slope –5
the standard point-slope form for an equation of a line y = mx + b
where m is the slope and b the y-intercept.
y = -5x + b Using ordered pair Pt(-10,1) to solve for b
1 = -5*-10 + b
-49 = b
y = -5x -49

Answer 3

u sure?

Answer 4

thx god ;)

Answer 5

Actually, y – 1 = –5(x + 10) and y = -5x -49 are the same.

Answer 6

so wich one would it be?

Answer 7

well if you expand y – 1 = –5(x + 10), you get y = -5x -49. I would use y = -5x -49 as the answer since it is in the standard form

Answer 8

ok thx :)

Answer 9

right
