Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
m = slope
The equation of the given line is
3x+y=10
y = - 3x + c
Comparing it with the slope intercept equation, slope, m = -3
If a line is parallel to another line, the slope of the line is the same with the slope of the given line. This means that the slope of the line passing through the point (-2,4) is -3
We would determine the intercept, c by substituting m = -3, x = -2 and y = 4 into y = mx + c. It becomes
4 = -3 × -2 + c
4 = 6 + c
c = 4 - 6 = - 2
The equation becomes
y = - 3x + - 2
It’s 2 bc that’s what I got
B. h=3/4 ( I Just worked this out)
Complete question :
a researcher compared the Heights and shoe sizes for 50 men, selected at random. The equation shown describes a line of best fit for the data, where X is the shoe size and y is the height, in inches (y=1.6x + 58)
Based on the equation, what is the approximate shoe size for a man having a height of 60 inches
Answer:
1.25
Step-by-step explanation:
Given the regression equation :
y=1.6x + 58
X = shoe size ; y = height
Using the equation, the approximate shoe size of a man with a height of 60 will be ;
60 = 1.6x + 58
60 - 58 = 1.6x
2 = 1.6x
2/1.6 = 1.6x / 1.6
x = 2 / 1.6
x = 1.25
Hence, approximate shoe size of a man with a height of 60 will be 1.25
