Answer:
Step-by-step explanation:
1.
y-intercept=-4
points: infinite points lies on it.,but one point (0,-4)
slope=3/5
2.
y-6=2(x+1)
y=2x+2+6
y=2x+8
y-intercept=8
slope=2
a point :(-1,6)
3.
y+4=2x
a point: (-2,-4) does not lie on it.
y -intercept=-4 (True)
a slope of 2 (True)
4.
y=-2/7 x
a slope of -2/7 (True)
a y-intercept of (0,0) (True)
no y-intercept (False), (0,0) is y-intercept.
5.
y+5=-(x-4)
a slope of -1
a point of (4,-5)
Examples of How to Find Unit Rate or Unit Price
Ryan purchased 3 apples for $1.80. What is the unit price, or the cost of one apple?
<span>We want to know the price per apple unit so we set up a ratio with the number of apples in the denominator. The total price goes in the numerator. So the fraction is 1.80/3.Complete the division: 1.80 ÷ 3 = .60. You can conclude that the per apple price unit rate is $0.60/1. Ryan paid a unit price of $0.60 per apple (60 cents per 1 apple = .60/1).</span>
The pottery store can make 176 coffee mugs in an 8 hour day. How many mugs can they make in one hour?
<span>We want to know the number of mugs made per hour unit so we set up a ratio with hours in the denominator. The total number of mugs made per day goes in the numerator. So the fraction is 176/8.Complete the division: 176 ÷ 8 = 22. You can conclude that the per hour mug-making unit rate is 22/1. The pottery store makes 22 mugs per hour (22 mugs per 1 hour = 22/1).</span>
Kylie can run 12 laps in 30 minutes. How many laps does she run per minute?
<span>We want to know the laps per minute unit so we set up a ratio with minutes in the denominator. The total laps goes in the numerator. So the fraction is 12/30.<span>Complete the division: 12 ÷ 30 = 0.4. You can conclude that the per minute lap unit rate is 0.4/1. Kylie can run 0.4 laps per minute (0.4 laps per 1 minute = 0.4/1).</span></span>
