Answer:

Step-by-step explanation:

To find the line y=mx+b we need two points. I choose (0,-2) and (1,0)

Since y=mx+b where m=slope and b=y intercept (value of y when x=0)

We have the point (0,-2) so we know b=-2

Now we find the slope which is defined as

m=(y2-y1)/(x2-x1), in this case

m=(0-(-2))/(1-0)

m=2, so the line is

y=2x-2

Write the equation of a line in general form with a point of (-3,0) and an undefined slope
horsena [70]

If the slope if is undefined, then the line is vertical.

The equation of a vertical line: x = a (a - any real number).

The line passes through the point (-3, 0) → x = -3 and y = 0.

Therefore we have x = -3.

The general form of a line: Ax + By + C = 0.

x = -3     <em>add 3 to both sides</em>

<h3>x + 3 = 0</h3>
