Here is the equation in point-slope form:
y - 22 = m(x - 0)
what is an equation in Point-slope form.
y - 22 = m(x - 0)
y - 22 = m(x - 0)
This equation represents a linear relationship between the number of days of rain (x) and the water level of the river (y).
y - y₁ = m(x - x₁)
where:
(x₁, y₁) is a point on the line and m is the slope.
We can use the points (3, 34) and (10, 62) to find the equation.
First, find the slope m:
m = (y₂ - y₁) / (x₂ - x₁)
m = (62 - 34) / (10 - 3)
m = 28 / 7
m = 4
Using point-slope formula with the point (3, 34):
y - 34 = 4(x - 3)
Solving it further:
y - 34 = 4x - 12
y = 4x + 22
Therefore, the equation in point-slope form is y = 4x + 22.
