The slope of the line through C(2, 5) and D(4,7) will be 1.
<h3>What is a linear equation?</h3>
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
Then the slope of the line through C(2, 5) and D(4,7) will be given as,
m = (y₂ - y₁) / (x₂ - x₁)
m = (7 - 5) / (4 - 2)
m = 2 / 2
m = 1
Thus, the slope of the line through C(2, 5) and D(4,7) will be 1.
