Plotting y-intercept= #5/2# and drawing 16 degrees angle towards positive x-axis.

Explanation:

Let's write the given equation in y = mx +c form
y = -#7/2#x + #5/2#
here the y intercept = #5/2#
Slope = -#7/2#x
graph{-7x-2y = -5 [-10, 10, -5, 5]}
Mark at 2.5 to mark the y-intercept. Since the slope is -7/2. #tan^-1# (7/2) = 74.04 degrees. Negative value of #tan^-1# (-7/2) = (180 - 76)= 106. Interior angle at 2.5 will be 16 degrees. Draw 16 degrees from 2.5 intercept. The line which passes through x-axis will be the required equation.
