Answer: m=1/2; b=-5
Step-by-step explanation:
We can use the given points to find slope, then use the y=mx+b equation to find the y-intercept. The formula for slope is .
Now that we know m=1/2, we can use that in y=mx+b to find the y-intercept. We can use any given point to plug into x and y.
y=1/2x+b [plug in x and y]
-2=1/2(6)+b [multiply]
-2=3+b [subtract both sides by 3]
b=-5
Now, we know that b=-5.
Answer:
gradient = 2
Step-by-step explanation:
calculate the gradient (slope) m using the slope formula
m =
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 3) ← 2 points on the line
m = = = = 2
Answer:
904.32
Step-by-step explanation:
I did the math
We have been given that Layana’s house is located at on a map. The store where she works is located at .
We are asked to find the distance from Layana’s home to the store
We will use distance formula to solve our given problem.
Let us convert our given coordinates in improper fractions.
Now we will use distance formula to solve our given problem.
Upon substituting coordinates of our given point in above formula, we will get:
Therefore, the distance from Layana's home to the store is 4 units and option A is the correct choice.
