Hi, from the question given that the yield of strawberry plant depends on the amount of fertilizer fed to the plants.
00:10
Agricultural research shows that an arc of strawberry plants will yield 70 cubic feet cubic feet of fertilizer will yield 560 pounds of strawberry.
00:42
Similarly, here 100 cubic feet of fertilizer will yield 800 pounds of strawberries.
01:03
So let x is the fertilizer and y represents the yield.
01:14
Here two points from the given information will be 70, 560 and 100, 800.
01:25
So from this we need to find the slope.
01:30
M is equal to y2 minus y1.
01:33
So this is x1, y1, x2, y2.
01:36
So 800 minus 560 divided by 100 minus 70.
01:47
So for further simplification we obtain slope is 3.
01:50
Now we know that the slope intersects from y is equal to mx plus b.
01:54
On substituting the points, so y is equal to first m is 3, x plus b...
