R×16=chairs.
We do this because if we multiply the rows of chairs (r) by how many are in each row (16) then we get our total amount of chairs.
Y=-1/3x+4
x2-x1/ y2-y1
(0,4)(2,-2)
2-0/-2-4
1/-3
y-intercept is 4
y=-1/3x+4
Vertical angles are always equal.
To find the value of y, compare the angles.
4y=2y+5
Subtract 2y from both sides
2y=5
Divide both sides by 2.
y=5/2
Option D is correct.
<h3>Answer:</h3>
- The line is horizontal.
- The rise is zero.
<h3>Explanation:</h3>
Slope is (rise/run). When it is zero, rise=0. A line with zero slope goes neither up nor down. It is horizontal, not vertical.
When run is zero, the line is vertical, and the slope is <em>undefined</em> (not <em>zero</em>).

Answer: y - 2 = - ¹/₅ ( x - 3 )</h2>
Step-by-step explanation:
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (3 - 2) ÷ ( -2 - 3)
= - ¹/₅
We can now use the point-slope form to write the equation for this line:
y - y₁ = m(x - x₁)
y - 2 = - ¹/₅ ( x - 3 )
