Archimedes

=Archimedes = Example  Y=X+2 Slope=1 Y-intercept=2 Word Problem:  Robert was trying to figure out both the slope of a mountain and its ski lodge on a graph. If the lodge was on the y axis perfectly aligned with the center of the mountain, it would be on the point -3. After reading the ski sign he finds the slope from his position is -4. What is the equation? The equation would be: Y=-3X+4 Problem: y=2x+3 to graph it look below at the picture. To change this back to the original problem from -6x=-3y+9 this is what you would do. -6x=-3y+9 (original equation) -6x-9=-3y+9-9(subtract 9 from both sides) -6x-9=-3y(rewrite equation after subtraction from both sides) -6x/-3-9/-3=-3y/-3(divide -3 from everything to get your final answer) 2x+3=y (final answer highlighted in yellow) =media type="custom" key="6261679" =
