f(x)=5/2x+3

Question

f(x)=5/2x+3

 

Answer 1

Assuming the function is f(x) = (5/2)x + 3, it is a linear function in slope-intercept form:

y = mx + b

The slope is 5/2, or 2.5, and the y-intercept is 3.

To graph the function, start at (0, 3). From there, move up 5 units and right 2 units to reach (2, 8). Draw a straight line through these points.

The x-intercept can be found by setting f(x) = 0:

0 = (5/2)x + 3

-3 = (5/2)x

x = -6/5 = -1.2

Answer: Slope = 5/2, y-intercept = (0, 3), and x-intercept = (-1.2, 0).
