Find the equation of a line passing through the point (2,1) with a slope of -1. Your final answer should be put into slope intercept form.

y= -x+3

Step-by-step explanation:

Here we can use the point slop formula y-y1 = b(x-x1)

now let b = the slope and plug in the given values

y-1 = -1(x-2)

simplify

y-1 = -x+2

put into slope intercept form

y= -x+3

correct

step-by-step explanation:

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
