Question

what are the x and y-intercepts of the line described by the equation? 3x - 9y = 10.8A) x-intercept = 1.2 y-intercept = 3.6B) x-intercept = -3.6 y-intercept = 1.2C) x-intercept = 1.2y-intercept -3.6D) x-intercept = 3.6 y-intercept = -1.2

Answer 1

we have the equation

3x - 9y = 10.8

Remember that

x-intercept ----> value of x when the value of y is zero

so

For y=0

substitute

3x-9(0)=10.8

3x=10.8

x=3.6

y-intercept -----> is the value of y when the value of x is zero

For x=0

3(0)-9y=10.8

-9y=10.8

y=-1.2

therefore

the answer is option D
