Equations written in slope-intercept form follow a specific format.
y= mx+ b
In this form, m represents the slope of the line and b represents the y-intercept. The given equation is already in this form, so we can highlight its slope and y-intercept.
y=-5/2x-7 ⇔ y= -5/2x+( -7)
The y-intercept is -7, so the graph passes through the y-axis at (0, -7). A slope of - 52 means that for every 2 units we move in the negative horizontal direction, we move 5 units in the positive vertical direction.
m= - 5/2 ⇔ rise/run=5/- 2
To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
