Answer:

Explanation:
All of these equations are in the 
 form.
 form. 
 stands for the slope (or gradient) of the line (how steeply it goes up or down) and
 stands for the slope (or gradient) of the line (how steeply it goes up or down) and 
 stands for the y value where the line crosses the y-axis (also known as y-intercept).
 stands for the y value where the line crosses the y-axis (also known as y-intercept). 
With this in mind, it's evident that the slope of 
 is 4 and that it crosses the y-axis when y is equal to -3.
 is 4 and that it crosses the y-axis when y is equal to -3.
Good luck!
