Aconstruction company completes two projects. the first project has $3,000 in labor expenses for 60 hours worked, while the second project has $2,100 in labor expenses for 42 hours worked. the relationship between the company’s labor expenses and hours worked is linear. which of the following would correctly calculate the y-intercept of the linear equation? select all that apply.

3,000 = 50(60) + b
3,000 = 0.02(60) + b
60 = 50(3,000) + b
2,100 = 0.02(42) + b
2,100 = 50(42) + b
42 = 50(2,100) + b
