Answer:
Step-by-step explanation:
5. You are asked to write an equation of the line in slope-intercept form, so you need to determine the slope of the line and the y-intercept.
You're lucky. One of the points, (0,1), has an x-coordinate of 0, so you know that the y-intercept is 1.
Use the coordinates of the points to determine the slope of the line.
slope = (difference in y-coordinates)/(difference in x-coordinates) = (10-1)/(3-0) = 9/3 = 3
The slope-intercept equation of the line is y = 3x+1

7. When x = 0, function A = 0 and function B = 3, so function B has a greater initial value.
Answer:
Step-by-step explanation:
Here the earlier price of the video game was $ 49 and now it's being sold for $ 300 . We need to calculate the percentage increase in price .
So the increase in cost is $( 300 - 49 ) = $ 251 .
So we can calculate the % increase as ,

Answer: y = —
x + 3
Step-by-step explanation:
The line crosses the y-axis at the point (0,3), making its y-intercept be +3.
The line is going downwards left to right, giving it a negative slope.
The line's slope is — because it is negative and it goes down 1, over 2.
Therefore, the line's equation is y = — x + 3
Answer:
<u>n= 4.5</u>
Step-by-step explanation:
The equation is:2(n-2)=5
Step 1- You need to do the parentheses.
The new equation is:
2n-4=5
Step 2-Next you add 4 to both sides of the equal sign.
The new equation is:
2n=9
Step 3- Now you divide by 2 into both sides and get the answer.
Answer:
<u>n=4.5</u>
