✒️LINEAR

» What is the equation of a line that has a slope of -3 and passes at point (2,3)?

• A. y= -3x - 7
• B. y= -3x + 7
• C. y= 3 - 7
• D. y = 3x + 7

» By according to the given, we can use the point-slope form to determine its linear equation in y-intercept form.

» Substitute the given in which m is the slope and (x1, y1) is the given point where the line passes.

The correct answer was not in the given choices. The answer is y = -3x + 9

Y= -3x+9

✒️Solution:

Substitute the given in which m is the slope and x1, y1 is the given point where the line passes.

• y-3=-3(x-2)
• y-3=-3x+6
• y=-3x+6+3
• y=-3x+9

» The True Answer Is y=-3x+9 But The Choices Is Wrong.
