9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9
Step-by-step explanation:
3 is cross multiplication
2 is proportion
and 1 is equal
527,381 + 364,098 = 891,479
1/2 radian ≈ 28.648°
Multiply by 180°/π to convert from radians to degrees.
