How do you convert 15x + 17y = 17 into slope intercept form?

y = -15/17x + 1

Step-by-step explanation:

15x + 17y = 17

17y = 17 - 15x

y = 1 - 15/17x

y = -15/17x + 1

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
