Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

nadya68 [22]

Option 1: $y = -3x+3$ is the right answer

Step-by-step explanation:

The slope-intercept form is given by:

$y = mx+b$

Here m is the slope and b is y-intercept

Given

m = -3

Point = (-1,6)

Putting the value of slope

$y = -3x+b$

To find the value of b, putting the given point (-1,6) in the equation

$6 = -3(-1) +b\\6 = 3 + b\\b = 6-3\\b = 3$

Putting the value of b in slope-intercept form

$y = -3x+3$

Hence,

Option 1: $y = -3x+3$ is the right answer
