Answer:
x-intercept = 6
y-intercept = -4
Slope: m = ⅔
f(3) = -2
Step-by-step explanation:
✔️The x-intercept is the value of x when y = 0. It is the point at which the line of the function intercepts the x-axis. Thus,
x-intercept = 6
✔️The y-intercept is -4. At this point, x = 0. The line intercepts the y-axis at y = -4. Thus,
y-intercept = -4
✔️Slope can be calculated using two points, (0, -4) and (6, 0).
Slope: m = ⅔
✔️f(3) means, what is the value of y when x = 3.
From the graph, when x = 3, y = -2.
Therefore,
f(3) = -2
