Answer:
The answer is A. Positive Weak Non-Linear
Step-by-step explanation:
The dotted points are graphed in an upward form which indicates that it's graphed positively but since the dotted points are scattered that indicates it has a weak "power".
To find the slope, we can use the formula m = y change/x change. Since we already have 2 points, we can subtract the second coordinates from the first ones.
1. (-18-(-18))/(15-6) = 0/9 = 0. m=0x
2. (16-12)/0-8) = 4/-8 = -1/2. m = -1/2x
Hope this helps.
Answer:
195
Step-by-step explanation:
15. 2x+4y=5
Since you want to put it into y-intercept format (y=mx+b) first you want to minus 2x on both sides making it 4y= -2x+5, following you will divide by 4 on both sides making it y= -1/2x+ 5/4(1.25). The slope being -1/2x and the y-intercept hitting 1.25 on the y-axis.
17. 3x-3y=5. Like question 15 you will have to put it into y=mx+b format. So first you would minus 3x on both sides becoming -3y = -3x+5 then do the following: divide by -3 on both sides making the answer Y= x-5/3(-1.66666667) you can round it up to -1.67. Overall the answer should be y=x-1.67. 1.67 being the y-int meaning the line meets the y-axis at 1.67 and the slope being 1/1 to help you form the line.
Answer:
B.
200x + 800 = 1,600; 4 months
Step-by-step explanation:
Since 200 is the amount you pay each month, and x is the months, we pay 200 dollars for each month. We also add 800 because that was the initial price she paid, which is known. We then complete the equation by making it equal to 1600 dollars, which is the total amount she paid.
When we get 200x + 800 = 1,600, we solve for x.
First, we minus 800 on each side to isolate x. 200x=1600-800
Then, we simplify, 200x=800
Lastly we divide by 200 on both sides to completely isolate x and complete the equation. 200x=800÷200
Simplify, getting x=4 (months)
Hope you understood!
