Answer:
Given in quesion:Point B (3,1) and point A is -1. Distance between A and B is 5 units.
Using distance formula for AB we obtain,
AB^2=(x2-x1)^2 + (y2-y1)^2
5^2=(3+1)^2 + (1-y)^2
25-16=(1-y)^2
9=(1-y)^2
1-y=3
y= -2
Therefore the possible co-ordinates of A are(-1,-2).This is your required answer.
Answer:
See below
Step-by-step explanation:
Equation: y = ![-\frac{2x^2}{21} + \frac{8x}{21} + \frac{43}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B2x%5E2%7D%7B21%7D%20%2B%20%5Cfrac%7B8x%7D%7B21%7D%20%2B%20%5Cfrac%7B43%7D%7B7%7D)
Slope-intercept form: ![y = \frac{2}{3} x + 1](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20x%20%2B%201)
Point slope form: ![y + 5 = \frac{10}{7} * (x+9)](https://tex.z-dn.net/?f=y%20%2B%205%20%3D%20%5Cfrac%7B10%7D%7B7%7D%20%2A%20%28x%2B9%29)
A ratio is a comparison of two values. In this case, there are 6 boys to every 15 girls. So, this means the ratio is 6:15.
Hopefully, this helps!
