The value of y so that the line passing through (-1, 9) and (2, y) has a slope of -2 is 3.
<h3>What is the slope of a line?</h3>
The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on a straight line, the slope can be determined using a variety of approaches.
, where and are two points on the line.
Two points (-1, 9) and (2, y) are given, and a slope of -2.
Put the points in the slope formula to get the value of y.
So, the value of y is obtained as 3.

Answer:
The domain of g(x) is all real numbers.
Answer:
15
Step-by-step explanation:
The base would be 3*3, as it's a square. There are 4 triangles, and the area of each triangle is 1*3/2=1.5. 1.5*4+9=15.
Both angles are the same so you do
5n-20=3n
-20=3n-5n
-20= -2n
n= -20 divide by -2
So n is -2
