EXPLANATION
The slope intercept form definition
y= mx + b is the slope intercept form of a line where m is the slope and b is the y -intercept
Slope between two points:
[tex]\text{Slope}=\frac{(y_2-y_1)}{(x_2-x_1)}[/tex](x1,y1) = (3,4) , (x2,y2) = (0,-2)
[tex]m=\frac{-2-4}{0-3}[/tex]Refine
m=2
The slope of the line that passes through the points (3,4) and (0,-2) is m=2
