Write an equation in point-slope form for the line through the point
(-2,1) parallel to the line with equation: 3x - y = -9. What would the coordinates be to graph both of the lines on one set of axes?
----------------------
Find the slope of the given equation:
y = 3x + 9
slope = 3
-------
Graph the given line::
Let x = 0, then y = 9
Let x = 3, then y = 18
-------------------------------------
Form of line with slope = 3 and passes thru (-2,1):: y = mx + b
Solve for "b":
1 = 3*-2 + b
b = 7
Equation: y = 3x + 7
Find 2 points and draw a line thru them::
Let x = 0, then y = 7
Let x = 3, then y = 16
----------
