-1=-2x+y

Slope intercept : y=2x-1

To find the slope-intercept form of the equation given, which is in the form y = mx + b, we need to isolate the y-variable on one side of the equation.

Given the equation -1 = -2x + y, we first need to rewrite it in the standard form, which is y = mx + b.
To do this, we can rearrange the equation by moving the y-term to the left side and the other terms to the right side:

-1 - y = -2x

Next, we can rearrange the equation to place the x-term in front of the -1:

-2x = -1 - y

Now, to isolate the x-term, we divide the entire equation by -2:

x = (-1 - y) / -2

Finally, let's rearrange the equation so that y is isolated on one side:

y = -(-1 - y) / 2

Now, simplify the equation:

y = (1 + y) / 2

Further simplifying, we get:

y = 1/2 + y/2

To isolate the y-term, we subtract y/2 from both sides:

y - y/2 = 1/2

To find a common denominator, we can express 1/2 as 2/4:

2y/2 - y/2 = 2/4

Combining similar terms on the left side, we get:

y/2 = 2/4

To simplify, we can multiply both sides of the equation by 2:

2(y/2) = 2(2/4)
y = 4/4
y = 1

Now we have the slope-intercept form of the equation:

y = 2x - 1
