Answer:

Step-by-step explanation:
The y-intercept is 2 and the line of symmetry is the y-axis.
Sure you could as long as you have the point.
for example let's say the slope is 2 and the point we are given is (4,4)
we know that:

plug in the values given
x=4
y=4
m=2

b, the y intercept equals -4.
so:

in this case
Step-by-step explanation:
y=4x+14
y=3x+15
-------------
y=7x+29
------------
7x+29
7x+29=0
7x=-29
7x/7=-29/7
x=-29/7
In this question, let's add those polynomials
(5x-6) + (2x-6)
5x -6 +2x -6 <em>Combine like terms</em>
<em>5x +2x -6-6</em>
7x -12
Since this is not an equation, no further step can be done.
