Question

What is the point-slope form of a line with slope-3 that contains the point (10,-1)?

Answer 1

Answer:

y = - 3x + 29

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation of the line

To find c substitute (10, - 1) into the partial equation

- 1 = - 30 + c ⇒ c = - 1 + 30 = 29

y = - 3x + 29 ← equation of line
