y = mx + b is standard form where m = slope
y = 0x -2 = -2
slope is zero; graph is a a horizontal line crossing y axis at -2 for all values of x

The slope is negative two over three. the y intercept is about negative 1.7.
negative two thirds
The slope is 2 and the y intercept is -3
Perpendicular lines have a negative reciprocal slope. Slope of y=2x+5 is 2/1 negative reciprocal is (-1/2)
If: 3x+y = -4 Then: y = -3x-4 and the slope of the line is -3
