Is y= x2-1 a linear equation

1 answer:

3 0

Answer: With the way you wrote it, I don't know. I'm assuming that it's $y=x^2+1$ . If that's the case, then no it's not linear.

Step-by-step explanation:

It's not a straight line. Graph it.

It's frustrating seeing questions like yours where the person asking literally does not even think through about their question. Next time, at least try the problem on your own instead of just deciding that you can't do it. This is an extremely easy problem, and I'm guessing you're just copying answers on here. The naivety here is palpable.

Answer:

y+5 = -3(x-1) point slope form

y = -3x-2 slope intercept form

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/ (x2-x1)

m = (7--5)/(-3-1)

= (7+5)/(-3-1)

= 12/-4

= -3

The slope is -3

Then we can use point slope form to write an equation

y-y1 = m(x-x1)

y--5 = -3(x-1)

y+5 = -3(x-1)

This is in point slope form

Distribute

y+5 = -3x+3

Subtract 5 from each side

y+5-5 = -3x +3-5

y = -3x-2

This is in slope intercept form
