y=-5/8x+17/4

Explanation:

.

m=-5/8

(2,3)

The general equation of a straight line is:

y=mx+b, where m is the slope and b is the y-intercept.

y=-5/8x+b

Now, we can use the coordinates of the point in this equation to solve for b:

3=-5/8(2)+b

3=-5/4+b

b=3+5/4=(12+5)/4=17/4

The equation of the line is:

y=-5/8x+17/4

y = -5/8 x + 17/4

Explanation:

usual equation is y= mx +b
substitute the values
3= 2(-5/8) + b
3=-5/4 +b
3+5/4=b
(12+5)/4 = b
17/4 = b
