Homework Statement
What is the vertical distance between the point A(−2,−3) and the line 2x+5y=3.
Homework Equations
The Attempt at a Solution
Here is what I did: I know its wrong.
First, changed the equation into proper form:
y = 2/5x - 3/5
Plotted the equation...
Then, I drew in the point (-2,-3). Then drew line from point, vertically to the line, just as a graphical representation.
so from the line, x = -2
So, If x = -2, then y would equal -1.4
So, then I put this into the distance formula:
[itex]\sqrt{}(-2 - (-2))^2 + (-1.4 - (-3))^2[/itex]
Which gave me 1.6
