umka2103 [35]

Answer:I don't know if you're asking for equation or not cause you didn't mention the question so I'm just gonna write down the equation.

y=4.2x+3.4

Use this formula➡️y=mx+b

m is slope, b is y-intercept , x and y are the points like (0, 3.4)

You said it's the y-intercept but it's not. it's just a point on the graph

In one week, Alex worked 35 hours at $ 12.50 per hour plus 5 hours overtime at 'time and half'. How much would Alex have earned
zvonat [6]
Find out how much Alex earned in 35 hours first.

1 hour = $12.50

35 hours = $12.50 x 35 = $437.50

Since ‘time and a half’ pays 1.5 times more than their usual pay, find out how much Alex earned per hour at ‘time and a half’

1 hour = 12.50 x 1.5 = $18.75

5 hours = 18.75 x 5 = $93.75

$437.50 + $93.75 = $531.25

Alex would have earned $531.25 for the week.
