Question

Determine the x- and y- intercepts for the graph defined by the given equation.
y = 7x + 3

Answer 1

intercept is 3

X intercept is -3/7

Answer 2

For this case we have the following equation:

`y = 7x + 3`

To find the y-intersection values we do
`x = 0`:

`y = 7 (0) +3\\y = 0 + 3\\y = 3`

To find the x-intersection values we do
`y = 0`

`0 = 7x + 3`

Subtracting 3 on both sides:

`-3 = 7x`

Dividing between 7 on both sides:

`x = - \frac {3} {7}`

So, we have:

x-intersection:
`(- \frac {3} {7}, 0)`

y-intersection:
`(0,3)`

Answer:

Option B
