The answers b. |3.7| = 3.7 so the answer will be 3.7
Answer:
Slope= 7/5
Step-by-step explanation:
The slope of a line is determined as a ratio of the change in y to the change in x.
Slope=Δy/Δx
Δy=y₂-y₁
Δx=x₂-x₁
Therefore we can use the the x and y coordinates from the points given, (-3,0) and (2,7) to calculate the slope.
m= (7-0)/(2-⁻3)
Slope= 7/5
When a negative number is subtracted from a number it the operation sign changes to addition.
Answer:
kinda hard
Step-by-step explanation:
1. -4y = 8x
y = -8/4x
y = -2x,,,,constant of variation is -2
2. slope = 2/3, y int = 9........y = 2/3x + 9 <==
3. (1,-3)(3,1)
slope = (1 - (-3) / (3 - 1) = (1+ 3) / 2 = 4/2 = 2
y = mx + b
slope(m) = 2
use either point (3,1)...x = 3 and y = 1
now sub and find b, the y int
1 = 2(3) + b
1 = 6 + b
1 - 6 = b
-5 = b
so ur equation is : y = 2x - 5 <==
