The graph is a horizontal line at y=3
if this is an x,y plot, it would be a vertical line at x = -3
7
Yes, it is a straight line
-2.25
No, they are perpendicular.
A horizontal line crossing the y axis at 3.
A horizontal line crossing the y axis at 3.
-1
y=-x Draw a straight line with slope -1 passing through (0,0). Or, plot (x,y) coordinates that satisfy the equation, and connect the dots.
The y intercept would be 3.
Any line with a slope of 1 is parallel to y=x-3.
The general equation of a straight line graph is y = mx + c, where m is the slope and c the intercept on the y axis. So the slope is 2, and the y intercept is -3. To plot, calculate y when x = -3: y = 2x - 3 y = 2*(-3) - 3 y = -6 - 3 y = -9, so plot the point (-3, -9) Now find y when x = 3: y = 2*3 - 3 y = 6 - 3, y = 3, so plot the point (3,3) Join the two points you have plotted, and there is your graph. Any point on this graph is a solution to your equation.
