The answer is (3,4) since x=3 and when the line is at x=3, it hits y=4. So the answer is (3,4).
Answer:
6.
Step-by-step explanation:
If each assignment is worth -3, you can divide 18 (amount of points changed) by 3 (each assignment's affect) to get 6.
Answer:
Step-by-step explanation:
6). Equation of the line has been given as,
4x + 9y = -9
By converting this equation into y-intercept form,
9y = -4x - 9
![y=-\frac{4}{9}x-\frac{9}{9}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B4%7D%7B9%7Dx-%5Cfrac%7B9%7D%7B9%7D)
![y=-\frac{4}{9}x-1](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B4%7D%7B9%7Dx-1)
By comparing this equation with y = mx + b
Here, m = Slope of the line
b = y-intercept
Slope of the equation (m) = ![-\frac{4}{9}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B9%7D)
y-intercept (b) = -1
8). Equation of the line is,
5x + 3y = 12
3y = -5x + 12
![y=-\frac{5}{3}x+\frac{12}{3}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B3%7Dx%2B%5Cfrac%7B12%7D%7B3%7D)
![y=-\frac{5}{3}x+4](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B3%7Dx%2B4)
Slope of the line = ![-\frac{5}{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B3%7D)
y-intercept = 4
The answer was is : The foot ball player is at school for 12 hours, I got this answer by multiplying 3 hours by 4 since 3 hours is a quarter and 4 quarters make up 100%.
The equation would be: 3x-5=40
