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
Answer:
0.73 meter board that Colin purchased will be left.
Step-by-step explanation:
Given : Colin meets three wooden boards to repair his porch.The length he needs are 2.2 meters,2.82 meters,and 4.25 meters.He purchases a board that is 10 meters long and cuts the three sections.
To find : how much of the board that Colin purchased will be left.
Solution : We have given
He needs 2.2 meters,2.82 meters,and 4.25 meters.
He purchased = 10 m long board.
Total board he needs = 2.2 + 2.82 + 4.25 = 9.27 meter.
Hence 9.27 meter board he need to use .
Board left = 10 - 9.27 = 0.73 meter.
Therefore, 0.73 meter board that Colin purchased will be left.
