First thing is to find the coordinates for the two points
(-3,-2) and ( 0,2)
Then we can use the slope formula to determine the slope
m = ( y2-y1)/(x2-x1)
= ( 2 - -2) / ( 0 - -3)
= ( 2+2) / (0+3)
= 4/3
The slope is 4/3
You can also count how many you go up and then how many you go over to get from the left point to the right point.
We go up 4 and then right 3
4/3
The y intercept is where it crosses the y axis.
It crosses at y =2
The slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = 4/3x +2
