8 is the x intercept and -2 is the y
Answer:
<h2>
y = -6x - 16</h2>
Step-by-step explanation:
The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:
m = -6
(-3, 2) ⇒ x₀ = -3, y₀ = 2
The point-slope form of the equation:
y - 2 = -6(x + 3)
So:
y - 2 = -6x - 18 {add 2 to both sides}
y = -6x - 16 ← the slope-intercept form of the equation
Answer:
The new TV screen is 12.1 centimeters wide.
Step-by-step explanation:
Find 10% of 11:
0.10 x 11 = 1.1
Add 1.1 to the original size.
11 + 1.1 = 12.1
