Question 4 is Choice A
Question 5 is Choice B
Question 6 is Choice C
Question 7 is Choice B
These are relatively simple it’s just understanding the relations of x and y values :)
Answer:b
Step-by-step explanation:If you multiply the top equation by -5 then you will have -5 +5, which is 0, therefore you are eliminating the x value
Answer:
y = 3/2x-5/2
Step-by-step explanation:
We have two points so we can write the equation for the line. (-1,-4) and (3,2)
First we can find the slope by using
m= (y2-y1)/(x2-x1)
m = (2- -4)/(3 - -1)
=(2+4)/(3+1)
= 6/4
= 3/2
Then put the slope into the slope intercept form of the equation
y= mx+b where m is the slope and b is the y intercept
y = 3/2x+b
We will use the point (3,2) and substitute it into the equation to find b
2 = 3/2(3)+b
2 = 9/2 +b
Subtract 9/2 from each side
4/2 -9/2 = 9/2-9/2 +b
-5/2 = b
y = 3/2x-5/2
