8x-y=-84 is t he equation for the provided points (12,-9) and slope will be 8 in point-slope form.
The general equation of a straight line is y = mx + c, where m stands for the gradient and y = c for the point where the line crosses the y-axis. This number c is referred to as the intercept on the y-axis. The equation for a straight line is y=mx+c. The variables c and m determine the y-intercept, sometimes referred to as the height where the line crosses the y axis. These lines have the equation y = mx + b, where m stands for slope and b for y-intercept.
Here,
provided point =(12,-9)
Slope m=8
(y-y1)=m(x-x1)
Slope
y-12=8x+72
8x-y=-84
8x-y=-84 in point-slope form will be the equation for the given points (12,-9) and slope (8).
