Final answer:
To find the missing y-value, we use the slope formula and substitute the given values. Simplifying the equation gives us the missing y-value of -17.
Step-by-step explanation:
To solve the equation and find the missing y-value, we can use the slope formula. The slope formula is given by:
slope = (y2 - y1) / (x2 - x1)
In this case, the given slope is 5/2 and one point on the line is (4,8). Let's call the missing y-value y. The other point can be represented as (-6, y). We substitute the values into the slope formula:
5/2 = (y - 8) / (-6 - 4)
Next, we simplify and solve for y:
5/2 = (y - 8) / (-10)
5/2 * (-10) = y - 8
-25 = y - 8
y = -25 + 8
y = -17
