Question

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

Answer 1

Answer:

 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: $(0,3)$

Option B
