Question

What is the slope and x and y intercepts on these graphs

Answer 1

Slope: -1

Y intercept: (0, -3)

X intercept: (-3, 0)

Explanation:

The slope of a function is calculated using the following formula:

`m=(y_2-y_1)/(x_2-x_1)`

To calculate the slope we use the indicated points (-4, 1) and (-2, -1), we substitute:

`m=(-1-1)/(-2-(-4))=(-2)/(-2+4)=(-2)/(2)=-1`

The y-intercept is when it crosses the y-axis and the x-intercept is when it crosses the x-axis.

Therefore:

Y intercept: (0, -3)

X intercept: (-3, 0)
