Which equation of a line passing through the point (-2, 2) with a y-intercept of 1?

Mathematics

Sholpan [36]3 years ago
7 0

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have y-intercept b = 1. Therefore y = mx + 1.

The graph passing through the point (-2, 2). Substitute the coordinates to the equation:

2 = m(-2) + 1       <em>subtract 1 from both sides</em>

1 = -2m      <em>divide both sides by -2</em>

m = -1/2

<h3>Answer: B. y = -1/2 x + 1</h3>

The midpoint is the middle, which is the average. So you would do 6.9+1.7 which is 8.6 then divide it by 2, giving you the answer 4.3.

4.3 inches of rainfall is the midpoint
