Question 316872
Write the standard form (ax+by=c) of the equation of the line with the following conditions. 
1. Through: (1,2) Slope; 7 
What i have tried: i have tried to graph it. i used the slope. And after that i got lost, because i dont understand the question itself.
-----------------------
Graphing it is ok, but it's not asked for.
You know the slope, m = 7, so find the y-intercept.
Use the point and y = mx + b to find b, the y-intercept.
2 = 7*1 + b
b = -5
-------
That makes the equation y = 7x - 5 in slope-intercept form
7x - y = 5 is the "standard form" asked for
-----------
7x - y = 5 is the answer.
