State the equation of a line that is perpendicular to the equation y = -1/2 x + 3 and going through the point (7,-1).

Respuesta :

Answer:

[tex]y=2x-15[/tex]

Step-by-step explanation:

1. The equation of the line in the slope-intercept form is [tex]y=3-\frac{x}{2}[/tex]

2. The slope of the perpendicular line is negative inverse: [tex]m=2[/tex]

3. So, the equation of the perpendicular line is [tex]y=2x-a[/tex]

4. To find [tex]a[/tex], the line should pass through the given point: [tex]-1=(2)(7)+a[/tex]

5. Thus, [tex]a=-15[/tex]

6. Therefore, the equation of the line is [tex]y=2x-15[/tex]

7. Answer: [tex]y=2x-15[/tex]
