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:
121 square feet
Step-by-step explanation:
The area of a triangle is the height multiplied by the base divided by 2. Since this is a right triangle, you can simply use the two legs for this. The area of this triangle is therefore:
Hope this helps!
Term = 5x^2
h = variable
21 is a constant
I think ab is an expression or the product of two factors.
Answer:
No
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.
The longest side = 61, thus
61² = 3721
12² + 60² = 144 + 3600 = 3744 ≠ 3721
Thus these sides do not form a right triangle.
