What us the y-intercept for 7x+2y=-10

FIrst we have to transform our equation into slope y-intercept form y=ab+x

7x+2y=-10 / - 7x subtract 7x both sides

2y=-7x-10 / : 2 divide by 2 both sides

y=-7/2-5

Now we can read value of parameter b, which is b=-5. Its the our result, so - 5.

Subtract 7x from both sides

2y = - 10-7x

sub 0 in for x

2y = - 10-7 (0)

divide both sides by 2

y = - 5
