1. Sketch the graph of the equation 2y + 3x = 1. Help with Steps Please? Anyone?
2. Determine the equation of the straight line through the point (-1, 5) with slope m = -1. Steps?
"1. Sketch the graph of the equation 2y + 3x = 1"
As this equation represents a line, finding two points and drawing the line through them will be enough. I would find the points where the line crosses the axes.
If I take ,
the equation will be, ,
So the point is
Similarly, If I take ,
the equation becomes, ,
So the point is
Now you can draw the axes, put the points and draw the line that passes on them.
"2. Determine the equation of the straight line through the point (-1, 5) with slope m = -1."
The general equation of line is . m is the slope of the line and C is a constant. Now, using the information given in the question, try to find C. Then there you found the equation
