Let x = 1. Substitute x = 1 into the equation:

y = -9X(1)+3

y = -9+3

y = -6

-> Ordered pairs are written in the form (x,y). Thus in this case, your ordered pair is (1,-6).

How to write slope-intercept form through (-1,3) and a slope of -1

oksian1 [2.3K]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = -1 and the point (-1, 3). Substitute:

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

$3=1+b$ <em>subtract 1 from both sides</em>

$2=b\to b=2$

<h3>Answer: y = -x + 2</h3>
