Find the x and y intercepts from the graph of the equation
Answer to Problem 52PPS
x − intercept is 7and y − intercept is − 2.
Explanation of Solution
Given:
The equation:
Concept Used:
The x -intercepts are where the graph crosses the x -axis, and the y -intercepts are where the graph crosses the y -axis.
Then, algebraically,
- an x -intercept is a point on the graph where y is zero, and
- a y -intercept is a point on the graph where x is zero.
More specifically,
- an x -intercept is a point in the equation where the y -value is zero, and
- a y -intercept is a point in the equation where the x -value is zero.
Calculation: The equation:
First we draw the graph and find the x and y intercept from the graph.
The x -intercepts are where the graph crosses the x -axis, and the y -intercepts are where the graph crosses the y -axis.
x − intercept point is (7,0) and y − intercept point is (0,− 2 )
Thus, x and y intercepts are x = 7 and y = − 2
