Answer:
y = 4x + 5
Step-by-step explanation:
The equation of a straight line line is;
y = mx + b
where m is the slope and b is the y-intercept
We start by calculating the slope value by using the slope equation
m = (y2-y1)/(x2-x1)
m = (9+ 7)/(1+ 3) = 16/4 = 4
So we have the equation as;
y = 4x + b
to get the value of b, we substitute the coordinates of any of the two points
let us use (1,9)
9 = 4(1) + b
b = 9-4
b = 5
so, we have the equation of the line as;
y = 4x + 5
Answer:
Step-by-step explanation:
Let us represent:
Short pieces = x
Middle pieces = y
Long pieces = z
A three foot long deli sandwich must be split into three pieces
x + y + z = 3
The middle piece is twice as long as the shortest piece
y = 2x
The shortest piece is 8 inches shorter than the longest piece.
x = z - 8
z = x + 8
We substitute
x + y + z = 3
x + 2x + x + 8 = 3
5x = 8 - 3
5x = 5
x = 5/5
x = 1
y = 2x
y = 2 × 1
y = 2
z = x + 8
z = 1 + 8
z = 7
How long should the three pieces be?
