algebra 1 hon - leith (lms)
topic 2: readiness assessment (lms graded)
write a linear equation that represents the ordered pairs shown in the table.

x	y
-1	5
0	1
1	-3
2	-7

(y = square x + square)

Explanation:

Step1: Identify y-intercept (b)

When $x=0$, $y=1$, so $b=1$.

Step2: Calculate slope (m)

Use points $(0,1)$ and $(1,-3)$:
$$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-3-1}{1-0}=-4$$

Step3: Plug into slope-intercept form

Slope-intercept form is $y=mx+b$.

Answer:

$y = -4x + 1$
