Question

How do you write the equation for intercept (4,-3), m=-1

Answer 1

Answer:

$\large\boxed{y=-x+1}$

Step-by-step explanation:

The slope-intercept from of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = -1 and the point (4, -3) → x = 4, y = -3.

Substitute to the equation:

$-3=(-1)(4)+b$

$-3=-4+b$   add 4 to both sides

$-3+4=-4+4+b$

$1=b\to b=1$
