For this case we have that by definition, the point-slope equation of a line is given by:
[tex](y-y_ {0}) = m (x-x_ {0})[/tex]
Where:
[tex](x_ {0}, y_ {0}):[/tex] It is a point through which the line passes
m: It is the slope of the line
According to the data we have to:
[tex](x_ {0}, y_ {0}): (-2,4)\\m = \frac {2} {5}[/tex]
Substituting:
[tex]y-4 = \frac {2} {5} (x - (- 2))\\y-4 = \frac {2} {5} (x + 2)[/tex]
Finally, the equation of the line is:
[tex]y-4 = \frac {2} {5} (x + 2)[/tex]
ANswer:
[tex]y-4 = \frac {2} {5} (x + 2)[/tex]
The equation representing the line is: [tex]\mathbf{y - 4 = \frac{2}{5}(x + 2)}[/tex]
Recall:
- Equation of a line can be written in point-slope form if we know the slope value (m) and a point (a, b) that the line passes through.
Given:
- A point on the line: (–2, 4)
- Slope of the line: [tex]\frac{2}{5}[/tex]
- Thus:
The equation in point-slope form of any line is:
[tex]y - b = m(x - a)[/tex]
- Where,
a = -2
b = 4
[tex]m = \frac{2}{5}[/tex]
- Substitute the values into the point-slope equation:
[tex]y - 4 = \frac{2}{5}(x - (-2))\\\\y - 4 = \frac{2}{5}(x + 2)[/tex]
Therefore, the equation that represents the line with a slope of 2/5 and passes through the point (-2, 4) is:
[tex]y - 4 = \frac{2}{5}(x + 2)[/tex]
