y=7x+1 ( apex )
If you mean 7 = 7x-3 then the perpendicular slope is -1/7 and the equation is y = -1/7x
x=10 For the equation -9 - 6x +7x = 1 First, add nine to both sides to get all of the x's on one side -9 - 6x + 7x = 1 +9 +9 -6x +7x = 10 Then, combine like terms on the left side -6x+7x=10 x=10

This is a linear equation. The value x = -1 is the solution to this equation.
the numbers 1 and 6 have an equation like this:(x+6)(x+1)=x2+7x+6=0
22=7x+1 (take 1 of each side of the equals) 21=7x (divide each side by seven) 3=x (BAM! answer)
The y-intercept for the equation y=-7x+1 is (0,1). When x=0, y= -7*0+1 = 1
It is solved when you have it in the form of (x = some number). In this case, you have 7x on one side, which is 7 times x. You need to divide both sides by 7, so you have: 7x / 7 = 7/7. On the left side, this becomes x. On the right side 7/7 = 1, so x=1 solves the equation. If you 'plug in' x=1 to the original equation, you get 7(1) = 7, or 7 times 1 equals 7, which is true.
To do this equation, you collect like terms. 7x-4x+x-15 is your original equation, you have 3 terms with "'x'" in them, and they are 7x, -4x, and x. 7x + (-4x) +x simplifies to 4x, because 7-4 = 3 + 1 = 4 (the x is really 1x....). After this, you get 4x-15, which is as simplified as this equation can be.
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
yes.
