Given the function f(x) =5/4 x -5 solve for the X- and y- intercepts use the interprets to graph the function .

Can anyone help me with this question please ?

Respuesta :

Answer:

y intercept = -5

x intercept = 4

Step-by-step explanation:

f(x) can be substituted with y for this question.

y = 5/4x - 5

the way to solve for x intercept is to set y to 0 and solve for x

0 = 5/4x - 5

5 = 5/4x

multiply by four on both sides

20 = 5x

divide by five on both sides

4 = x

the way to solve for the y intercept is to set x to 0 and solve for y

y = 5/4(0) - 5

y = -5

you can then graph the points (4,0) and (0,-5) to create the line for the function.
