Question

Write in point-slope form an equation of the line that passes through the point (1,9) with a slope of -2

Y-_=_(x-_)

Answer 1

y - 9 = - 2(x - 1)

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = - 2 and (a, b ) = (1, 9 ) , then

y - 9 = - 2(x - 1) ← is the equation of the line
