The linear equation that best fits the data is: y = 10x + 15.
<h3>How to Write the Linear Equation of a Data?</h3>
First, find the slope/unit rate (m) and the y-intercept/starting value, then substitute the values into y = mx + b.
Using two points on the graph, (1, 25) and (2, 35), find the slope (m):
Slope (m) = (35 - 25)/(2 - 1)
Slope (m) = 10/1
Slope (m) = 10
Substitute (x, y) = (1, 25) and m = 10 into y = mx + b to find b
25 = 10(1) + b
25 - 10 = b
b = 15
Substitute m = 10 and b = 15 into y = mx + b
y = 10x + 15

The slope-intercept form of a line:
m - slope
b - y-intercept
Convert 2x + 3y = -6 to the slope-intercet form:
<em>subtract 2x from both sides</em>
<em>divide both sides by 3</em>
Let and
We have
Therefore
We have the equation of a line:
Put the coordinates of the point (0, 0) to the equation:
Answer:
If I'm thinking correct it would say 5 120. HOPE I HELPED>
Answer:
<h2>w=6</h2>
Step-by-step explanation:
7w-6=3w+18 I expanded the bracket
+6 on both sides
7w=3w+24
-3w on both sides
4w=24
divide both sides by 4
w=6
Answer:
30,000
Step-by-step explanation:
50% remaining = 10500
After deposit: 2×10500 = 21000
210000 : 70%
X : 100%
21000/70 = X/100
X = 30,000
