Write an equation of the line in slope-intercept form. JY 1 (3, 3) (0, 2) 2 4<br>y=​
stellarik [79]

Correct answer: y = \frac{1}{3}x + 2

To find out the slope, you would need to remember this slope formula: \frac{y_{2}-y_{1}}{x_{2}-x_{1}}. We can use the two points provided on the graph to figure out the slope. We can label (3, 3) as x_{1} and y_{1}, and (0, 2) as x_{2} and y_{2}. Now we can plug these numbers into the slope formula to find out the slope:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} → \frac{2-3}{0-3} → \frac{-1}{-3} → \frac{1}{3}

To find out the y-intercept, just substitute (3, 3) into the slope-intercept<em> </em>formula ( <em>y = mx + b</em> ) with the slope that is substituted for '<em>m</em>' that we already solved earlier.

y = mx + b

(3) = \frac{1}{3}(3) + b

3 = 1 + b

2 = b

You can also prove this true by looking at the graph provided. The line intersects at the y-axis at 2.

Now we know that m = \frac{1}{3} and b = 2, we can substitute it into the slope-intercept formula. Thus, the answer is y = \frac{1}{3}x + 2.

Hope this helps you! Let me know if you have any more questions related to this problem.

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.00. They spend
Tatiana [17]

。☆✼★ ━━━━━━━━━━━━━━━  ☾

Subtract the cost of the pizza from the total:

16.95 - 12 = 4.95

Divide this value by 3:

4.95/3 = 1.65

1 large drink cost $1.65

PLEASE HELP ASAP!!
Airida [17]

Answer:

C

Step-by-step explanation:

Hey There so the first step of this problem is to find the formula for circumference

C=2\pi r

given some of the values we can form an equation to solve for the radius (r)

31.4=3.14(2)r\\3.14(2)=6.28\\31.4=6.28r\\\frac{31.4}{6.28} =5

so we can conclude that the radius is equal to 5
