Given the point (2, 3) and the slope of 4, find y when x = 22.
Solution:
Given, the slope m = 4
The point is (2, 3)
We have to find y when x = 22.
The equation of a line passing through a given point is given by
\((y-y_{1})=m(x-x_{1})\)
Now, \(\\(y-3)=4(x-2)\)
y - 3 = 4x - 8
y = 4x - 8 + 3
y = 4x - 5
Put x = 22 to find the value of y,
y = 4(22) - 5
y = 88 - 5
y = 83
Therefore, the value of y when x = 22 is 83.
Given the point (2, 3) and the slope of 4, find y when x = 22.
Summary:
Given the point (2, 3) and the slope of 4, when x = 22, y = 83.
