Centre of circle: (2, 1.25) Slope of line: 9/4 Equation of line: y-1.25 = 9/4(x-2) => 4y-5 = 9x-18 => 4y = 9x-13
Points: (2, 3) and (11, 13) Slope: 10/9 Equation: 9x = 10x+7

This is a linear equation. The value x = -1 is the solution to this equation.
9
Write the given equation in the slope-intercept form, y = mx + b, where m is the slope of the line.9x - 3y = -81 (subtract 9x to both sides)-3y = -9x - 81 (divide by -3 to both sides)y = 3x + 27Thus, the slope of the line is 3.
9 is.
In the equation y = mx + b, m is the slope. To convert 9x - 3y = 10 to y = mx + b: 9x - 3y = 10 Subtract 9x from both sides: -3y = -9x +10 Divide both sides by -3: y = 3x - 10/3 The slope of this line is 3.

Slope: -9
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
Centre of circle: (2, 1.25) Slope of line: 9/4 Equation of line: y-1.25 = 9/4(x-2) => 4y-5 = 9x-18 => 4y = 9x-13
9x-4y=7 in slope intercept form
Put in this form to see. Y = mX + c9X + 3Y = 63Y = - 9X + 6Y = - 3X + 2=========The slope of the line you seek is - 3.
-9/4 or -2.25
If you mean y = -9x+11 then it is a straight line equation whereas -9 is the slope and 11 is the y intercept
