Blakey + 2 = -x - 4
The elegant way to graph it is . . .
- Subtract 2 from each side of the equation: y = -x - 6 - The slope of the line is -1 and the y-intercept is -6.
- Put a dot at y=-6 on the y-axis, and draw a line with a slope of -1 through the dot.
The easy way to graph it is . . .
-- Pick any number for 'x'.
-- Substitute it for 'x ' in the equation and solve for 'y'.
-- Pick any other number for 'x'.
-- Substitute it for 'x' in the equation and solve for 'y'.
-- Now you know two points on the line. Draw a dot at each point, draw the line between them, and keep going as far as you want in each direction.
