to find the slope and y-intercept, solve for
=> slope is and y-intercept is
and draw graph

Solve for y
7x + 8y = 16
8y = -7x + 16
y = -7x/8 + 16/8
y = (-7/8)x + 2
Compare this to y = mx+b to find...
m = -7/8 = slope
b = 2 = y intercept
------------------------------
To graph this, plot the point (0,2) to represent the y intercept.
Then move down 7 and right 8 due to the slope. This should have you go from (0,2) to (8,-5)
Plot the points (0,2) and (8,-5). Draw a straight line through them.
Desmos is a handy graphing tool I recommend. Another useful graphing tool is GeoGebra.
If you prefer a TI83 or similar, then stick to that option.

Ax + By = C and draw graph.

-----------which is now in slope-intercept form.
Plot the point (0, C/B) and use the slope to identify one or more
other points; and draw the line through the points.
