Question 96751

{{{7*x+8*y=56}}} Start with the given equation


To find the y-intercept, let x=0 and solve for y:

{{{7*(0)+8*y=56}}} Plug in {{{x=0}}}


{{{8*y=56}}} Simplify


{{{x=56/8}}} Divide both sides by 8




{{{y=7}}} Reduce




So the y-intercept is (0,7) (note: the y-intercept will always have a x-coordinate equal to zero)
