Question 200959
Find an equation of the line having the given slope and containing the given point.
M=6/7, (4,-8)
---
Form of the equation : y = mx + b
You are told m = 6/7 and that y = -8 when x = 4; 
solve for "b":
-8 = (6/7)4 + b
b = -8 - (24/7)
b = -80/7
-------------
The equation of the line is y = (6/7)x -(80/7)
-------------------------------------- 
Find the intercepts and then use them to graph the equation
1.2x-1.7y=4.08
---
x-intercept:
Let y = 0 then x = 4.08/1.2 = 3.4
=================================
y-intercept:
Let x = 0 then y = 4.08/-1.7 = -2.4
========================================
Graph:
{{{graph(400,300,-10,10,-10,10,(1.2/1.7)x - (4.08/1.7))}}}
================================================================
