Question

Graph the ordered pairs for y = 3x + 3 using x={−2,  1, 2}

Answer 1

ANSWER

See graph

EXPLANATION

We need to find the y-values for the ordered pairs by substituting the x-value in to the relation

when
$x = - 2$
$y = 3( - 2) + 3$

$y = - 6 + 3$

$y = - 3$

This gives the ordered pair
$(-2,-3)$

when
$x = 1$

.
$y = 3(1) + 3$

$y = 3 + 3$

$y = 6$
This also gives the ordered pair

$(1,6)$

when
$x = 2$
$y = 3(2) + 3$

.
$y = 9$

This also gives the ordered pair,
$(2,9)$

We now plot all the ordered pairs and draw a line through them.

Answer 2

These are the answers hope it helps


y= -3

y= 6

y= 9
