y=2x-6
Points: (-5, 9) and (-4, 7) Slope: -2 Equation: y = -2x-1 in slope intercept form
We know that its slope is negative, but without an equation or some points the line passes through we can't determine the actual value of the slope.
You know your slope by finding two points on a line P1(x, y) and P2(x, y) and use the following equation:m = (y2 - y1)/(x2 - x1).'m is the sloporput the line in the form y = mx + C, where m is the slope and C is the y-intersection length
Point-slope form is just another way to express a linear equation. It uses two (any two points that fall on the line) and the slope of the line (Therefore the name point-slope form).y2 - y1 = m(x2 - x1)...with m as the slope.
The slope of a line that has the points 3, (-4), and has a slope of 2 is 2.

If you mean a slope of 4 and points of (0, 2) then the equation is y = 4x+2.
Points: (4, 9) Slope:3 Equation:- y-9 = 3(x-4) y = 3x-12+9 y = 3x-3 in slope intercept form
Points: (-2.5, -0.5) and (4.5, -1) Slope: -1/14 Equation: y = -1/14x-19/28 in slope intercept form
Slope=8 point=(-7,3)
If you mean a slope of 3 and a point of (3, 9) then the equation is y = 3x-3
In the case that you are using Slope-Intercept Form, no, you only plot two points: the y-intercept and one other point. If you don't use Slope-Intercept Form, then you have to use three points.
