10x + 4y = 20<br> what are the x and y intercepts and why

Murrr4er [49]

Answer:

To find the x-intercept, set $y = 0$

and solve for $x$ .

$10x + 4y = 20 \\ 10x + 0 = 20 \\ 10x = 20 \\ x = 2 \\(2 ,0)$

To find the y-intercept, set $x = 0$

and solve for $y$ .

$10x + 4y = 20 \\ 0 + 4y = 20 \\ 4y = 20 \\ y = 5 \\(0,5)$
