Solve. Answer using slope-interecept form.
In slope-intercept form, write the equation of a line that goes through point (0, -2) and (2, -5).
Equation:
1. |
Calculate the slope using
(x1, y1)
= (0, -2) and
(x2, y2)
= (2, -5) |
|
m |
= |
y2 - y1
x2 - x1 |
= |
-5 - (-2) 2 - 0 |
= |
-3 2 |
|
2. |
Take what you know and plug it into the point-slope formula |
|
y - y1 |
= |
m |
(x - x1 ) |
y - (-2) |
= |
-3 2 |
(x - 0) |
|
3. |
Put the equation in slope-intercept form by solving for y |
|
y + 2 |
= |
-3 2 |
x |
y |
= |
-3 2 |
x - 2 |
|
The answer is
