Slope intercept form:
y=mx+b
Where:
m= slope
b= y-intercept
For: y=1/2x-2
slope = 1/2
b= -2
To graph it we have to look at the y-intercept.(-2) It means that the line crosses the y axis at y=-2.
looking at the slope, we know that slope = rise (y) / run (x). 1/2
For every 2 units along the x-axis (to the right) the line goes up by 1 unit.
Since inequality has a y> the line is not included in the solution, so it's a dashed line, where the solution is above the line.
8x - 10 = 86 {combined like terms}
8x = 96 {added 10 to both sides}
x = 12 {divided both sides by 8}
3x - 5 = 31 {substituted 12, in for x, into 3x - 5}
width = 12 in.
length = 31 in.
Answer:

A.) From the resulting plot, tbe slope of the graph is positive, hence, we can conclude that there exist a positive relationship between the variables 'promote' and 'sale'.
The linear trend line gives the best fit for the data with a correlation Coefficient, R value of 0.5935
The R² value is 0.3522. R² is the Coefficient of determination which gives the percentage of explained variation. For this data, about 35% of variation in sales is given by the best fit line.
