Linear Relationships Test

Salima writes a blog about video games. She currently has 65 subscribers to her blog. Her plan is to add 12 new subscribers every month from now on. If all goes according to her plan, which linear equation represents the total number of subscribers y to Salima's blog after x months?

• y= 65x + 12

• y = 65 x - 12

• y= 12x + 65

• y = 12x - 65
