A line with a slope of 3 passes through (2,5). Which choice is an equation of this line? Please help
jek_recluse [69]

Answer:

Top right.

Step-by-step explanation:

So we want a line with a slope of 3 and passes through (2,5).

To do so, we can use the point-slope form.

The point-slope form is:

y-y_1=m(x-x_1)

m is the slope and x₁ and y₁ is an ordered pair.

Thus, let m be 3, y₁ be 5, and x₁ be 2. Thus:

y-5=3(x-2)

Our answer is the top right :)
