i have to use the slope equation for 62and 04 i have to use

i have to use the slope equation for (-6,-2)and (0,4) i have to use the formula to determine the slope of the line between each air of paints

slope=(y2-y1)/(x2-x1)

slope=(4--2)/(0--6)
slope=(4+2)/(0+6)
slope=6/6
slope=1

Furthermore...
The equation for any line is
y=mx+b
m=slope=1
y=x+b
b=y-intercept This is the position of y when x=0.
You provided this as (0,4)
y=x+4
is the formula for this line.
