Find the slope of the line perpendicular to 7x-2y=3.

To start, first convert 7x-2y=3 from standard form to slope intercept form. To do this, first subtract over 7x to get -2y=-7x+3. Then, divide both sides by -2 to get 
y=7/2x-3/2
Now that you have this in slope intercept form, take the m value of the equation, 7/2 and find the negative reciprocal of it. This will be the value of the slope of a line perpendicular to 7x-2y=3. Your final answer will be -2/7.

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
