Answer:
y = 2/3x -20/3
Step-by-step explanation:
The perpendicular line will have a slope that is the opposite of the reciprocal of the slope of the given line:
-1/(-3/2) = 2/3
You can use the point-slope form to write the equation of that perpendicular line.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +2 = 2/3(x -7) . . . . . the equation of the perpendicular line
__
This can be put into slope-intercept form by solving for y and simplifying.
y +2 = 2/3x -14/3
y = 2/3x -20/3
Answer:
7.7
Step-by-step explanation:
23/3 = 7.66. 7.66 rounded to the nearest tenth is 7.7

Answer:
The slope of the line between these two points is 1.50.
Step-by-step explanation:
The general form of the regression line is:
Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>m</em> = slope
<em>c</em> = intercept.
The formula to compute slope using two-point method is:
In this case the dependent variable is the cost per week to feed and independent variable is the weight of the hamster.
The two points are:
(<em>x</em>₁, <em>y</em>₁) = (3, 3.50)
(<em>x</em>₂, <em>y</em>₂) = (4.8, 6.20)
Compute the slope as follows:
Thus, the slope of the line between these two points is 1.50.
Multiply. Distribute 3x to all terms in the parenthesis: x and -8
3x(x) = 3x²
3x(-8) = -24x
3x² - 24x is your answer
hope this helps
