Slope:
Y-intercept:
Equation:
is this graph proportional? _____
Answer:
Slope: 1
Y-Intercept: (0,4)
Equation: y=1x+4
Step-by-step explanation:
To solve for slope you need to pick 2 points on the graph (ex. 2,6 and 4,8 ), then you use the formula to find the slope.
For Y-Intercept you just look for where the line intercepts on the y-axis (ex. 0,4).
If the line doesn't touch the origin (0,0), then it isn't proportional.
For the equation it's y=mx+b or, if its proportional then y=mx. The Y-Intercept will always be b. The slope represents m. The x is the variable.

Walter and Denise ordered a dessert to share at a restaurant. If Denise ate 1 8 of the dessert and Walter ate 4 5 of the dessert, what fraction of the dessert was left over?
Answer:
3/40
Step-by-step explanation:
Walter and Denise ordered a dessert to share at a restaurant. If Denise ate 1/8 of the dessert and Walter ate 4/5 of the dessert, what fraction of the dessert was left over?
Let the total dessert be represented as = 1
The fraction of the dessert left over =
1 - (4/5 + 1/8)
Lowest Common Denominator = 40
1 - (4 × 8 + 1 × 5/40)
1 - (32 + 5/40)
1 - 37/40
Lowest Common Denominator = 40
40 × 1 - 37 × 1/40
40 - 37/40
= 3/40
Therefore, the fraction of dessert that is left over = 3/40

Assume the following sequence is arithmetic: 4, 12, …. Write an equation (rule) for this arithmetic sequence.
I am not sure exactly what the question is asking...
12 - 4 = 8, so the difference between 4 and 12 is 8.
If you were to keep writing the sequence it could go like this, “4, 12, 20, 28...” and so on, adding 8 every time.
Let me know if you need any more help!
If given points A at (6, 3) and B at (-1,4), determine AB
HELP ASAP
Answer:
AB = 5[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A(6, 3) and (x₂, y₂ ) = B(- 1, 4)
AB = [tex]\sqrt{(-1-6)^2+(4-3)^2}[/tex]
= [tex]\sqrt{(-7)^2+1^2}[/tex]
= [tex]\sqrt{49+1}[/tex]
= [tex]\sqrt{50}[/tex]
= 5[tex]\sqrt{2}[/tex] ← exact value

How does the percent equation relate proportional quantities?
Answer: Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
