Well, let's take a moment to look at this equation together. If we substitute 8 for x in the equation y - 9x - 1, we get y - 9(8) - 1. Simplifying that gives us y - 72 - 1. So, the expression becomes y - 73. It seems like there might have been a little mistake in the equation, but that's okay! Let's keep practicing and learning together.

No because without an equality sign the given expression can't be considered to be a straight line equation.
The 'answer' is the number that 'x' must bein order to make the statement true.-9x + 1 = -80Subtract 1 from each side of the equation:-9x = -81Divide each side by -9 :x = 9
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
273x+1 = 9 33(3x+1) = 32 9x+3 = 2 9x = 2-3 9x = -1 x = -1/9 Check: 27(3*-1/9)+1 = 9
Points: (1, 9) and (0, 0) Slope: 9 Equation: y = 9x
1. Write the equation in y=mx+b. 2. b is the y-intercept. Ex. 1. y=9x+0 2. b=0. The y-intercept of y=9x is 0. Hint: Since this is a direct variation problem (y=kx), the x-intercept is also 0.
