Question

Find an equation of the line passing through the point (4,3) with slope m=3

Answer 1

Use the formula y=mx+b in order to solve for b. Then, plug in known values.

y=3x−9

Answer 2

Answer:

y=3x-9

Step-by-step explanation:

Enough information is given to write the line's equation in point slope form:

$y-y_1=m(x-x_1)\\'m' - slope\\(x_1,y_1) - coordinate$

The slope is three and the point is (4,3).

Replace the equation with the given information:

m = 3

x1 = 4

y1 = 3

$y-3=3(x-4)$

We can also make the equation into a slope intercept equation:

$y-3=3(x-4)\\\rightarrow y-3=3x-12\\\rightarrow y-3+3=3x-12+3\\\boxed {y=3x-9}$

So, the equation would be $y=3x-9$.
