Question

Write an equation in slope-intercept form of the line that passes through the given points.

Answer 1

Answer:

y=-5/2x-1

Step-by-step explanation:

We can just use two of the points to find the equation

I am going to use (0,-1) And (-2,4)

Slope = y2-y1/x2-x1

Which is

4+1/-2+0

This can result in

-5/2

Thus the slope is -5/2

Now the equation looks like this in slop intercept form:

y=-5/2x+b

We need to find b or the y-intercept so we use one of the points to substitute our x and y.

I am going to use (0,-1)

Which is

-1=b

Thus b is -1

The equation is

y=-5/2x-1

Hope this helps!
