Answer:
y = 4x + 14
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 7 ← is in slope- intercept form
with slope m = 4
• Parallel lines have equal slopes , then
y = 4x + c ← is the partial equation
to find c substitute (- 3, 2 ) into the partial equation
2 = - 12 + c ⇒ c = 2 + 12 = 14
y = 4x + 14 ← equation of parallel line
Answer:
49
Step-by-step explanation:
48+ 5 = 53 divided by = 49
In any linear equation the coefficient of the x-term represents ALWAYS the slope.
So it is B. The slope of the line
Answer:
1. the plants grew 50%
2. if the plants grew to be 8 inches instead of 9 the they would have grown 33% which is less than 50%
3. 100% increase

First, we need to find the base. To do so, we will need to use the Pythagorean Theorem on one of the smaller triangles to solve for its unknown side. Then, we can double the base of the one to find the base of the whole.
Pythagorean Theorem: a^2 + b^2 = c^2
(12)^2 + b^2 = (16)^2
144 + b^2 = 256
b^2 = 112
b = 
b = 
total base = 2 x
= 
Second, we can find the area. The formula for the area of a triangle is A = 1/2 x base x height.
A = 1/2 x
x 12
A =
x 12
A =
units^2
Third, we can find the perimeter. The perimeter is the sum of all of the exterior sides.
P = 16 + 16 +
P = 32 +
units
