I need help on understanding how to find the solution. All answers will be helpful and I appreciate all of you for your explanations.
(-3, -3), perpendicular to y-7/3x+3.
I am assuming that the equation is...
If not, please let me know.
The slope of this line is 7/3.
The slope of the line perpendicular to this is the negative inverse; -3/7.
y=(-3/7)x+b is a formula written in slope-intercept form.
You need point-slope, especially since the y-intercept, value of b, is still unknown.
Subtracting a negative is the same as adding a positive.
Let's subtract 3 from both sides as we proceed to isolate y...
Considering the fact that 3=21/7...
