Question

Write an equation in point slope form for the line through the given point with the given slope (-10,-1) m=-1

Answer 1

Answer:

y + 1 = -(x + 10)

Step-by-step explanation:

• Point-Slope Form: y - y1 = m(x - x1)

The given coordinate (-10, -1) are your (x1, y1), so:

• x1 = -10
• y1 = -1
• m =  -1

All you have to do is substitute the given information into the formula:

• y -(-1) = -1(x -(-10)), which will simplify to y + 1 = -(x + 10)

Remember: Double negatives make a positive so if the given coordinates for (x1, y1) are negatives, they will be added to y or x in point-slope form, not subtracted.
