Question

On the graph of the equation 3x+ 2y=18, what is the value of the y-intercept?

A) -9
B) -6
C) 6
D) 9

Answer 1

y = 9

Explanation:

3x + 2y = 18

required:

find the y-intercept

we have to eliminate x to get the y intercept value

3(0) + 2y = 18

2y = 18

y = 18/2

y = 9

so the x & y intercept would be (0, 9)

Answer 2

D) 9

Explanation:

`3x+ 2y=18\\\\Let \:x\:equal\:to\:0\\\\3(0)+2y=18\\\\0+2y=18\\\\2y=18\\\\Divide \:both\:sides\:of\:the\:equation\:by \:2\\(2y)/(2) =(18)/(2) \\\\y =9\\(0,9)`
