Question

Write in point-slope form an equation of the line that passes through the point (4,4) with a slope of 3.

Answer 1

Answer:

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

Step-by-step explanation:

Point-slope form is represented by the formula $y-y_1 = m (x-x_1)$. Substitute the $m$, $x_1$, and $y_1$ in the formula for real values in order to write the equation of a line in point-slope formula.  

$m$ represents the slope, thus substitute 3 for it. $x_1$ and $y_1$ represent the x and y values of one point the line intersects. So, use the x and y values of the point (4,4) for the formula. Substitute 4 for $x_1$ and 4 for $y_1$. This gives the following answer and equation in point-slope form:

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