Answer: y= 3x-1
Step-by-step explanation:
Equation of a straight line:
y = mx + b ------(i)
Step by Step Solution:
Step 1: Calculating Slope (m).
m =
y2-y1
x2-x1
m =
2--1
1-0
m =
3
1
m = 3
Now putting value of m in equation (i)
y = 3x + b -----(ii)
Step 2: Calculating Y-intercept (b).
Lets choose the first point, (0,-1) for calculating y-intercept:
y = mx + b
-1 = 3(0) + b
-1 = 0 + b
-1 = b
b = -1
Answer:
432 ft²
Step-by-step explanation:
The formula of finding the area of a trapezoid: (base 1 + base 2/ 2) x h
(base 1 + base 2/ 2) x h
= (20 + 28/2) x 18
= 24 x 18
= 432 ft²

Step-by-step explanation:
Answer: 6
Step-by-step explanation:
0, 3, 4 , 6, 6, 7, 7, 9
6+6= 12
12 ➗ 2 = 6
Answer:
z = - 24
Step-by-step explanation:
Given
- 0.4(0.5z + 4) = 3.2 ( divide both sides by the multiplier - 0.4 )
0.5z + 4 = - 8 ( subtract 4 from both sides )
0.5z = - 12 ( divide both sides by 0.5 )
z = - 24
