ABSOLUTELY CORRECT, BUT THAT IS THE LONGEST WAY TO DETERMINE THE SHORTEST DISTANCE FROM A POINT TO A LINE. HOWEVER, THAT COULD BE BETTER IF ONE HAS NO IDEA THAT A DISTANCE FORMULA FOR THIS SITUATION DO EXIST.

You can draw a parallel lines to the perendicular right and left.This means another parallel line would be drwan to the line already existed. Then it is found that all of them except perpendicular would be hypoteneuse and certainly would be larger in length.

(2,0) 3x-4y+15=0 I changed it to y=mx+b form and got y=3x+3.5 then I tried to get an equation that intersects the line that is formed by the given equation. I got y=-1/3x+b I tried to find b I got -2/3 took both equations I got to equal each other (excluding y values) 3x+3.5=-1/3x+-2/3 solved. x=-25/8. Also known as -3.125 plugged my x value to one of the equations to get a y value. y= -2.375 used the distance equation d=√(x²-x¹)² + (y²-y¹)² plugged in the coordinates and got 7.627048905 I look at the answer key and I see 21/5. My answer is wrong. I need help

Huria iqbal you can also solve this by using another method : you have a point (2,0) and you have a line 3x-4y+15=0 (if the line is not in general line form, you need to rewrite it as that)(general line form: Ax+by+c=0) then you use d=|Ax+by+c| / √(A^2 + B^2) then you get d= |6+0+15| / √(9+16) which equals to 21/5
