Write an equation of the line containing the point (2,1) and perpendicular to the line 5x – 2y = 3.

So first, you want to isolate your Y. To do this, you must get it alone on ONE SIDE of the equation.

5x - 2y = 3

-5x         -5x

=

ANSWER: y = \frac{3-5x}{-2}

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

i belive those are the ones that are under 90 degreese.
