Answer:
![y=-\frac{5}{2}x+\frac{45}{2}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B2%7Dx%2B%5Cfrac%7B45%7D%7B2%7D)
Step-by-step explanation:
The slope intercept form of a line is given as:
y = mx + c
Where m is the slope and c is the y-intercept
Let's rearrange the equation given in this form:
2x - 5y = -11
5y = 2x + 11
y = 2/5 x + 11/5
So the slope is 2/5
Slope of line that is perpendicular to this is the "negative reciprocal" of this slope. Which means the slope of perpendicular line would be -5/2
Thus, equation would become: y = -5/2x + c
Now we need to find c. For this we plug in 7 into x and 5 into y and solve for c [(7,5) is the point given]. Thus,
![y=-\frac{5}{2}x+c\\5=-\frac{5}{2}(7)+c\\5=-\frac{35}{2}+c\\c=5+\frac{35}{2}\\c=\frac{45}{2}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B2%7Dx%2Bc%5C%5C5%3D-%5Cfrac%7B5%7D%7B2%7D%287%29%2Bc%5C%5C5%3D-%5Cfrac%7B35%7D%7B2%7D%2Bc%5C%5Cc%3D5%2B%5Cfrac%7B35%7D%7B2%7D%5C%5Cc%3D%5Cfrac%7B45%7D%7B2%7D)
Thus, the equation of perpendicular line is:
![y=-\frac{5}{2}x+\frac{45}{2}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B2%7Dx%2B%5Cfrac%7B45%7D%7B2%7D)
