Question

What is an equation of a line, in point-slope form, that passes through (1, -7) and has a slope of -2/3?

O y-7= -2/3( x + 1)
Oy+7= -2/3(x - 1)
Oy+7=2/3(x + 1)
O y-7=2/3(x-1)

Answer 1

second option

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)/(3)` and (a, b ) = (1, - 7 ) , then

y - (- 7) = -
`(2)/(3)` (x - 1) , that is

y + 7 = -
`(2)/(3)` (x - 1)
