Question 96753
{{{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)
