If you mean: y = mx+b then it is in slope intercept form
Use the slope intercept form equation, y=mx+b. Plug in -2 for m and 8 for b. Final equation: y=-2x+8
In slope-point form a line with slope m through point (X, Y) has equation: y - Y = m(x - X) → y = mx + Y - mX → y = mx + c where: m is the slope c = Y - mx is the intercept → The line with slope 2 through the point (1, 1) has equation: y = 2x + 1 - 2×1 → y = 2x - 1

Technically, a-2b=2 is the actual answer. Since you wouldn't have to put it in y=mx+b form, the equation can no longer be simplified.
If you mean: y = mx+b then it is in slope intercept form
No, y=x^2 + 2 is a quadratic equation. A linear equation is one in the form y=mx+b. A quadratic has a form y=ax^2+bx+c.

The slope-intercept form of an equation is: y = mx + b Just copy down this equation, then replace "m" with the slope, and "b" with the y-intercept.

1.Put into y=mx=b 2.graph 3. find ordered pair where the lines intersect
An equation such as y = mx + c is said to be in standard form. From such an equation, Gradient = coefficient of x = 3
b=-2
The equation of a line written in slope intercept form has the form of y = mx + b. In this form, m is the slope of the line and b is the y intercept.
You know that an equation has no solution when...Ex. 2>5 is falseTo show its false, put and O with a / through it----------To find it false, in terms of graphing, it is when you have parallel lines (Not crossing at any point if, in a perfect world, the lines went on forever).So for an exampley=2-3x6x+2y=7 (y=-3x+7/2 in Y=mx+b form)With this equation the lines do not pass through each other, and once more in a perfect world, if they kept going on the lines would never cross.
