How do you graph the function y=3x-4?

May 27, 2017

$y$-intercept is $- 4$

And for every $x$-value there would be an increase of $3$ in the $y$ value

Explanation:

Choose $x$ values and work out the $y$ values.

$x \rightarrow y$
$0 , - 4$
$1 , - 1$
$2 , 2$
$3 , 5$
$4 , 8$
$5 , 11$
$6 , 14$
$7 , 17$
$8 , 20$
$9 , 23$
$10 , 26$

Now plot the points and join them with a straight line.

Whenever there's an increase in the $x$ by $1$,. there will be an increase in $y$ by $3.$
