Question

If 5x + ky = 35 and the y-intercept = 5, what is k?

Answer 1

Answer:

k=7

Step-by-step explanation:

Given equation: 5x+ky=35

Step 1: Substitute 7 for k: 5x+7y=35

Step 2: Subtract 5x from both sides: 7x=-5x+35

Step 3: Divide both sides by 7: y=-5/7+5

Step 4: Check if 5 is at the end of the equation

Answer: k=7
