The slope-intercept form: y = mx + b
m - slope
b - y-intercept
We have 2(x - 1) = y + 3 <em>use distributive property</em>
(2)(x) + (2)(-1) = y + 3
2x - 2 = y + 3 <em>subtract 3 from both sides</em>
2x - 5 = y → y = 2x - 5
slope: m = 2
y-intercept: b = -5
x-intercept for y = 0. Substitute:
2x - 2 =0 <em>add 2 to both sides</em>
2x = 2 <em>divide both sides by 2</em>
x = 1
<h3>Answer:</h3><h3>slope = 2</h3><h3>y-intercept = -5</h3><h3>x-intercept = 1</h3>
-------------------------------------------------------------
y = 2x + 1
slope: m = 2
y-intercept: b = 1
x-intercept for y = 0. Substitute:
2x + 1 = 0 <em>subtract 1 from both sides</em>
2x = -1 <em>divide both sides by 2</em>
x = -0.5
<h3>Answer:</h3><h3>slope = 2</h3><h3>y-intercept = 1</h3><h3>x-intercept = -0.5</h3>
Minus 3/2 both sides
k=14-3/2
k=12+4/2-3/2
k=12+1/2
k=12 and 1/2
Answer:
3=11
Step-by-step explanation:
Start of by doing -2-1
The line of best fit is a line that follows the direction of the dots. It doesn't have to be perfect, it's just a general line to represent the data. Sometimes there isn't a line of best fit (if there is no correlation). It normally touches most of the dots.
The slope is about 1/2 and the point where the line touches the y axis is at 40 so that means an equation could be y = 1/2x + 40
When the advertising expenditure (x value) is 18,000, substitute it into the equation above. y = 1/2(18,000) + 40 which equals y = 9,040 . This is the expected revenue.
Hope this helps!
Tawny can fill 8 glasses with juice. This is because there are 16 fluid ounces in one pint. 16 x 2.5 is 40 and 40 divided by 5 is 8.
