Question

Can someone please help me with the problem below. Please I will fan and medal

Answer 1

im having trouble finding the slope

Answer 2

The very important one is that when x=0, y=3.

Answer 3

yup

Answer 4

Then, just use (2,-7).
-7=(slope)(2)+3
Subtract 3 from both sides
-10=(slope)(2)
Divide each side by 2
slope=-5

Answer 5

So the function is f(x)=-5x+3

Answer 6

Oh I see thank you so much

Answer 7

Here's our function

\[y = m(x)+b \]

where m = slope
b = y intercept.

b is important because that's where x = 0.

so you know that when x = 0, y must be 3

so far you would get

y = m(x)+3

now for the slope m

we can take any two points on the graph and subtract the y values and x values.

\[m = \frac{ y_{2}-y_{1} }{ x_{2}-x_{1}}\]

Answer 8

thank you
