Answer:
Step-by-step explanation:
To find the equation of line m (the perpendicular line), you will need to find the negative reciprocal of the slope of line y.
The slope of the original line is -2/5, so the negative reciprocal would be 5/2.
Now that you have the slope of line m, the equation is y=(5/2)x+b. To find the value of b (the y-intercept), plug the point (-1, 1) into this equation for y and x and solve for b.
1=(5/2)(-1)+b. After solving for b, the value of b is 7/2.
Now plug this back into your equation for line m.
The answer is y=(5/2)x+7/2.
