Answer:

The equation of the line in slope-intercept form is

#y = -7/2 x + 9 1/2#

Explanation:

The slope intercept form of a line is #y=mx+b#

For this problem we are given the slope as #-7/2# and a point on the line of #(1,6)#

#m=-7/2#
#x=1#
#y=6#

We plug in the values and then solve for the #b# term which is the
y-intercept.

#6 =-7/2(1) +b#

#6 =-3 1/2 +b#

Now isolate the #b# term.

#6 +3 1/2 =cancel(-3 1/2) cancel(+3 1/2)+b#

#b= 9 1/2#

The equation of the line in slope-intercept form becomes

#y = -7/2 x + 9 1/2#
