Are you supposed to do all the ones in the quotations?
Answer:
x=
−1
2
y+
25/2
Step-by-step explanation:
Let's solve for x.
2x+1y=25
Step 1: Add -y to both sides.
2x+y+−y=25+−y
2x=−y+25
Step 2: Divide both sides by 2.
2x
2
=
−y+25
2
x=
−1
2
y+
25
2
There's a strong negative association between the two variables.
An equation that passes through the coordinates (3, -1) and has a slope of 2 would be y=2x-7 because since the slope is positive and is 2/1 the slope rises by 2 and runs 1 to right and eventually passes (3, -1) when it starts at -7 on the y-intercept. Answer: y=2x-7
