Find the slope intercept equation of the line containing (2, -3) and having slope m= 4

erica [24]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 4. Substitute:

$y=4x+b$

Put the coordinates of the point (2, -3) to the equation of a line:

$-3=4(2)+b$

$-3=8+b$ subtract 8 from both sides

$-11=b\to b=-11$

<h3>Answer: y = 4x - 11</h3>
