So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
Answer:
4.) Choice B
&
5.) Choice A
Step-by-step explanation:
<em><u>Question 4:</u></em>
First you have to solve for y to get slope intercept form.

The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.
<em><u>Question 5:</u></em>
For this one I we will use this formula 
I will choose the easy pairs to plug it in 

The slope is a fraction again but you can convert it and that'll be Choice A.
X² - 3x - 4 = 0
Reverse FOIL method . . .
(x - 4)(x + 1) = 0
one of the paranthesis has to be equal to zero if the other is not . . .
x - 4 = 0
<u><em>x = 4</em></u>
x + 1 = 0
<u><em>x = -1</em></u>
Answer:
26s+24
Step-by-step explanation:
2(3s+9) +2(10s+3)
6s +18+20s +6
26s +24= perimeter
