Question

X+y=-1 in slope intercept form

Answer 1

y = -x - 1

Explanation:

To write this equation in slope intercept form, we will first familiarise ourselves with the formula.

The formula for slope intercept is y = mx + b, where the parameter m tells us the slope and the parameter b tells us the y-intercept of the line.

If we know these two parameters, we have enough information to write the equation of the line.

So now let's rewrite the equation "x + y = -1" in "y = mx + b" form.

x + y = -1

y = -1 - x

y = -x - 1

Answer 2

y = -x - 1

Explanation:

Slope intercept form is y = mx + b, where m is the gradient/slope and b is the y-intercept

x + y = -1 needs to be rearranged so that y is the subject. This can be done by subtracting x from both sides: y = -x - 1

Hope this helps!
