Question 1092827
Write the equation of the line perpendicular to 3y -x = 2 and passing through (9, -10)
<pre>To obtain the equation of a line that's perpendicular to another, we do the following: 
<b>1)</b> Put GIVEN equation in STANDARD form
<b>2)</b> Switch coefficients on variables, and change the constant to z
<b>3)</b> Negate y
<b>4)</b> Substitute GIVEN point to determine z
These steps should lead you to the required equation: {{{highlight_green(matrix(1,3, 3x + y, "=", 17))}}}
