Question

The equation of a function is y = -1/3 x - 2/5. Find i) the value of y when x = 0. ii) the value of x when y = -2/3

please do it step by step and quick ​

Answer 1

i) the value of y when x = 0.

y = -1/3 x - 2/5

y = -1/3 *0 - 2/5

y= 0-2/5

y= -2/5

ii) the value of x when y = -2/3

y = -1/3 x - 2/5

-2/3 = -1/3 x - 2/5

1/3x= -2/5 + 2/3

1/3x = 4/15

x= 4/15*3

x= 4/5
