Question 391304
If thia model is linear, you need to change the d to x and w to y:
x=2y+50

Since y is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
2y+50=x

Since 50 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 50 from both sides.
2y=-50+x

Move all terms not containing y to the right-hand side of the equation.
2y=x-50

Divide each term in the equation by 2.
(2y)/(2)=(x)/(2)-(50)/(2)

Simplify the left-hand side of the equation by canceling the common factors.
y=(x)/(2)-(50)/(2)

Simplify the right-hand side of the equation by simplifying each term.
y=(x)/(2)-25

To find the slope and y intercept, use the y=mx+b formula where m=slope and b is the y intercept.
y=mx+b

Using the y=mx+b formula, m=(1)/(2) and b=-25.
m=(1)/(2), b=-25
