Find an equation of a line that goes through (4,1) and is perpendicular to the line x - 3y = 9. DO NOT USE THE POINT SLOPE METHOD, use the Slope Intercept method demonstrated.

y = -3x + 13

Step-by-step explanation:

For slope-intercept form, you need the slope and the y-intercept.  To find the slope, you need to rearrange the given equation to slope-intercept form.

x - 3y = 9

-3y = -x + 9

y = 1/3x - 3

The slope for the given equation is 1/3.  The slope of a perpendicular line will be the negative reciprocal.  This means that the slope of the perpendicular line will be -3.

You can now solve for the y-intercept (b) using the slope (m) and the given point in slope-intercept form.

y = mx + b

1 = (-3)(4) + b

1 = -12 + b

13 = b

b = 13

Now that you have both the slope and y-intercept, you can find the equation.

y = -3x + 13

your answer is b ^w^ hope i
