Graphing Linear Equations

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

y = 3/4x + 3

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

The y-intercept is the value of y when x = 0, represented by b in the equation.

The slope is -1, which is the coefficient of x.

The graph is a straight line that crosses the y-axis at (0, 2) and has a slope of -1.

y = 1/2x represents a line with a positive slope.

The equation is y = -2x + 4.

Start at the y-intercept (0, -3) and use the slope (rise/run = 2/3) to find another point.

Two lines are parallel if they have the same slope but different y-intercepts.
