Answer:
y=-3x-2
Step-by-step explanation:
step 1- find the slope
parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3
step 2- use the point slope form which is y-y1=m(x-x1)
and substitute in the numbers (only substitute y1,x1, and m)
m is the slope which we found to equal -3
x1 and y1 are the points that they gave us (-2,4) are (x1,y1)
x1=-2
y1=4
step 3- substitute
y-y1=m(x-x1)
y-4=-3(x-(-2))
simplifies to y-4=-3x-6
add 4 to both sides to get y=-3x-2
Answer:
d = 4
Step-by-step explanation:
C = 2*pi r or C = pi * d
Area = pi *r^2= pi (d/2)^2 = pi * d^2 /4
So if they are numerically equal, you get
pi * d = pi * d^2 / 4 Divide both sides by pi
d = d^2 / 4 Multiply both sides by 4
4*d = d^2 Divide both sides by d
4 = d
Answer: 1; -5
Step-by-step explanation:
For this problem, we are asked to find the slope and y-intercept.
We see that this linear line goes through the y-axis at (0,-5). therefore, our y-intercept is -5.
To find the slope, we would use the formula 
. We can use the points (0,-5) and (5,0) since we can clearly see the line goes through these 2 points.
From our formula, we found that the slope is 1.
For the first box, you would fill in 1, the slope. The second box would be -5, the y-intercept.
That would be (20+30+56)/200 = 106/200 = 53/100 Answer
