Refer to the Explanation.

Explanation:

#y=7x+3# is a linear equation in slope-intercept form, #y=mx+b#, where #m# is the slope and #b# is the y-intercept.

Since it's a linear equation, you only need two points.

Points
#x=0,# #y=3#
#x=-1,# #y=-4#

Plot the points on the graph and draw a straight line through the points.
