Hello Could You Please Help Me On Questions 2 And 4 I Dont Understand Them class=

Sagot :

Given:

2. (2, 4), slope 2

we will write the equation of the line that passes through the point (2, 4) and has slope = 2

We will write the equation of the line using the point-slope form which is:

[tex]y-k=m\cdot(x-h)[/tex]

where (m) is the slope and the point (h, k)

so,

m = 2

h = 2

k = 4

So, the equation will be:

[tex]\begin{gathered} y-4=2(x-2) \\ y-4=2x-4 \\ y=2x \end{gathered}[/tex]

so, the answer will be the equation of the line is:

[tex]y=2x[/tex]
