Question

Please help me with thisEXTRA POINTS!!

Answer 1

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

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

$y=mx+4$

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

y = -1 and x = 2:

$-1=2m+4$     subtract 4 from both sides

$-5=2n$     divide both sides by 2

$-\dfrac{5}{2}m$

Answer: $f(x)=-\dfrac{5}{2}x+4$

Answer 2

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.
