Hello there! :)
Given:
x-coordinate of point = -2
y-coordinate of point = 5
Slope, or "m" = 1/5
Substitute in these values into slope-intercept formula (y = mx+b)
5 = 1/5(-2) + b
5 = -2/5 + b
25/5 = -2/5 + b
27/5 = b
Rewrite the equation:
y = 1/5x + 27/5
Graph the equation using a graphing utility:
Answer:
The equation that represents the line passing through the point (2, -4) with a slope of one half is
Step-by-step explanation:
The equation of a line can be described by a first order equation in the following format:
In which a is the slope of the line.
Solution:
The line slope is , so
.
The equation of the line now is:
The problem states that the line passes through the point(2,-4). This means that when x = 2, f(x) = -4
So:
So, the equation that represents the line passing through the point (2, -4) with a slope of one half is
