Answer:
y = 1/2x +2
Step-by-step explanation:
y-y1= m (x-x1)
first find slope
m= 4-1 / 4 - (-2)
m= 3 / 4+2
m= 3/ 6
m = 1/2
you can pick any of the two points to solve for point slope form
y-4 = 1/2 (x-4)
y-4= 1/2x -2
add 4 on both sides
y = 1/2x +2
y-1= 1/2 (x- (-2))
y-1= 1/2 (x+2)
y-1= 1/2x +1
add 1 on both sides
y= 1/2x +2
you should get the same answer with any of the two points you chose
you might want to use a calculator to solve this
if you want to use both points to make sure the answer is correct, you can
if you don't get the same answer with both points then u did something wrong during the equation.
Answer:
Step-by-step explanation:
Area of figure = area of rectangle 1 + area of rectangle 2 +area of rectangle 3 +area of triangle
= 5*5 + 9*16 +20 * 8 + (1/2) * 3* 3
= 25 + 144 + 160 + 4.5
=333.5 sq. in
a) replace x with -10 and solve:
-6(-10)-3 = 60-3 = 57
f(-10) = 57
b) replace f(x) with 93 and solve for x:
93 = -6x-3
Add 3 to each side:
96 = -6x
Divide each side by -6:
x = -16
The input value is -16
