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.

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
