Question

Graph ​ y=−56x−4 ​.

Use the line tool and select two points on the line.

Answer 1

56 is the slope
and -4 is the y intercept 
so you first graph 0,-4 
then use the slope and move 56 units up and one to the right 

Answer 2

5/6 is the slope
and -4 is the y intercept 
so you first graph 0,-4 
then use the slope and move 5 units up and 6 to the right
