Step-by-step explanation:
Our coordinates are (6, 0) and (0, -3).
We can use the formula (y₂-y₁)/(x₂-x₁) to find the slope-intercept form (y=mx+b)
Now, we plug the coordinates into the formula and solve.
(0-(-3))/(6-0)
=3/6
=
So, the slope is .
Now, we have to find the y-intercept, which is the point where the line on the graph intersects with the y-axis.
We can find the y-intercept (which is represented by b) by plugging the information we already know into the formula.
We can use either pair of coordinates for the formula, so I'll use (6, 0).
y=mx+b
0=(6)+b
Now, we can solve.
0=3+b
Subtract 3 from both sides.
-3=b
The y-intercept is -3.
Answer:
y=x-3
Answer:
492.99
Step-by-step explanation: x = amount invested at 12%
y = amount invested at 9%
---
x + y = 20287
0.12x = 0.09y + 492.99
---
put the system of linear equations into standard form
---
x + y = 20287
0.12x - 0.09y = 492.99
Answer:
(-4,4)
Step-by-step explanation:
<h3>The equation represents the total amount Emma earns at the event is y = 10x</h3>
<em><u>Solution:</u></em>
Given that,
<em><u>The total amount Emma earns, y, is proportional to the number of bracelets, x, she sells</u></em>
Where,
y is the total amount Emma earns
x is the number of bracelets
k is the cost of each bracelet
<em><u>Emma earns $10 for each sold bracelet</u></em>
Therefore, k = 10
Thus, eqn 1 becomes,
<h3>y = 10x</h3>
Thus the equation represents the total amount Emma earns at the event is found
