Question

Please!1

Use the given equation to find the missing coordinates of the points and then find the slope of the line for each equation.
y - -3/7x+3, A(..., 6), B(9, ...)

Answer 1

Explanation:

Slope = m = -3/7

`y=(-3)/(7)x+3\\\\\\Substitute \ y =6 \ and \ find \ the value \ of x\\\\6=(-3)/(7)x+3\\\\\\6-3=(-3)/(7)x\\\\\\3=(-3)/(7)x\\\\\\3*(7)/(-3)=x\\\\\\x=-7`

A(-7,6)

`Substitute \ x=9 \ and \ find \ value \ of y\\\\y=(-3)/(7)*9+3\\\\\\y=(-27)/(7)+3\\\\\\Multiply \ the \ entire \ eaution \ by \ 7\\\\7y =7*(-27)/(7)+7*3\\\\\\7y=-27+21\\\\7y=-6\\\\ y =(-6)/(7)`

B(9 , -6/7)
