Solution
for this case we can create the following diagram
We can find the slope between (4,0 ) and (5,4) and we have:
[tex]m=\frac{4-0}{5-4}=4[/tex]Then we can use the point (-1,0) and one corrdinat eof the point is (?,4) since needs to be at the same level (5,4)
And we can do this:
0= 4*-1 +b
b= 4
And the equation is:
y= 4x+4
And solving for x we have:
4= 4x+4
4x=0
x=0
And the point is:
D.(0,4)
= 4x+
