Question 1205757
<font color=black size=3>
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...
<font color=red>m = -7/8 = slope
b = 2 = y intercept</font>


------------------------------


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.
