Concept explainers
To graph the equation then state the slope and y- intercept of line.
Answer to Problem 36SGR
Graph of the given equation:
y-intercept of line is -2.
Slope of the line is 4.
Explanation of Solution
Given information: Linear equation
Solution:
In order to graph the line, we need to get two points.
Plugging x=0 in given equation
We got first coordinate (0, -2).
Now, plugging x=2 in given equation
So, we got second coordinate (2, 6).
Draw a line by joining the points
From the graph, we can see that line crosses y-axis at -2. Therefore, y-intercept is -2.
Now, if we go 4 units upward and 1 unit right, we get another coordinate (1, 2).
So the slope will be
Therefore, slope of the line is 4.
