Answer: y=-5
Step-by-step explanation:
Ok so for number 5, AB is proportional to BC just like PQ is proportional to QR. AB = 9, BC = 15, PQ = 3, and QR = x. 9/15 = 3/x. Cross Multiply: This gives you - 9x = 45. Divide both sides by 9, and you get x = 5. QR = 5
The answer will be: Y = -2/5x - 4
Slope intercept form: y= Mx+b
You find the slope (M) using: rise/run formula
You find (b) by looking at the y-intercept
