I can't help you with your graphing tool. With my graphing tool, the graph looks like this.
The vertex is at (-4, -1), and it goes through the point (-3, 1).
Answer:
6,764 coins
Step-by-step explanation:
76 bags of coins x 89 coins per bag = 6,764 total coins
The interest that Brain would receive is $12.03.
<h3>How much interest would Brain receive?</h3>
The interest received is a function of the amount saved, interest time and the length of time the money was saved.
Interest = amount saved x number of months x (annual interest rate / 12)
$875 x 3 x (0.055 / 12) = $12.03

Understand that the graph of a</span>proportional relationship<span> is a line through the origin whose slope is the unit rate (constant of proportionality)</span>
Answer:
Step-by-step explanation:
- Firstly, plug in the point and slope into the slope-intercept equation format:
When lines are parallel to one another, their slopes are the same. But they have different y-intercepts. To explain further, slope is the angle of measure of a line from a horizontal standpoint and knowing that parallel angles must have the same angle, it can be concluded that parallel lines would have the same slope or in other words, an equal slope.
Now solving, use algebraic concepts:
11 = -8(-1) +b (Now solve for b)
11 = 8 + b (Subtract 8 from both sides) (Use the "Right" to "Left")
-8 -8
3 = b (Switch terms)
b = 3
Now let's write the equation with only slope and y-intercept.
Getting the result of:
y = -8x + 3
