It took Greg 95 minutes to run his errands.
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find the totaltime Greg spent running errands,
We need to calculate the difference between his departure time from work and his arrival time at home.
First,
We can convert both times to minutes past midnight to make the calculations easier.
So,
4:42 pm = 4 × 60 + 42 = 282 minutes past midnight
6:17 pm = 6 × 60 + 17 = 377 minutes past midnight
To find the time Greg spent runningerrands, we can subtract his departure time from his arrival time:
= 377 - 282
= 95 minutes
Therefore,
It took Greg 95 minutes to run his errands.

The slope-intercept form is
y = mx + b,
where m = slope, and b = y-intercept
Now we get the y-intercept and the slope from the graph.
The y-intercept, b, is 4.
To find the slope, start at (-2, 0). Go up 4 and right 2 to point (0, 2). That is a rise of 4 and a run of 2.
m = slope = rise/run = 4/2 = 2
Equation:
y = mx + b
y = 2x + 4
Answer: y = 2x + 4
