The slope-intercept form:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept → (0, b)

From the graph we have the y-intercept 4. Therefore

[tex]y=mx+4[/tex]

Find other point → (2, -1). Put the coordinates of the point to the equation.

y = -1 and x = 2:

[tex]-1=2m+4[/tex]     subtract 4 from both sides

[tex]-5=2n[/tex]     divide both sides by 2

[tex]-\dfrac{5}{2}m[/tex]

Answer: [tex]f(x)=-\dfrac{5}{2}x+4[/tex]

Answer:

f(x) = -5/2x + 4

Step-by-step explanation:

First, you need to put the correct numbers in slope intercept form which is y = mx + b

m = slope

b = y intercept

b = 4

We have 2 points which is 2, -1.

Do the steps below:

Subtract 4 and then divide by 2 to each side of the equation.
