Question 1)
x-intercept is the point where the line cross x-axis. From the graph we can see that the line crosses x-axis at x = -6.
y-intercept is the point where the line cross y-axis. From the graph we can see that the line crosses y-axis at y = 6.
So, x-intercept is (-6, 0) and y-intercept is (0, 6)
Question 2)
Using the two intercepts, we can find the slope(m) of line.
This means, the slope of line is 1.
Question 3)
We have slope and y-intercept. So the equation of line in slope intercept form will be:
y=1(x) + 6
y = x + 6
In standard form the equation will be:
x - y = - 6
x-intercept is the point where the line cross x-axis. From the graph we can see that the line crosses x-axis at x = -6.
y-intercept is the point where the line cross y-axis. From the graph we can see that the line crosses y-axis at y = 6.
So, x-intercept is (-6, 0) and y-intercept is (0, 6)
