Answer:
Slope= 1/2x
Y-intercept= -3
Explanation:
The slope intercept form is defined as y = mx + b
Where m = slope (or change in y-coordinate/ change in x-coordinate)
and b = y-intercept (or where the graph crosses the y-axis)
In this particular equation... The slope (1/2x) represents a vertical change of 1 unit for every 2 units changed horizontally
It is also important to note that the negative stays with the 3 when defining b.
Therefore... the slope is 1/2x and the y-intercept is -3
