Hello,
1) Finding the slope of the line passing throught the 2 points:
m=(-8-6)/(7-2)=-14/5.
A perpendicular line has a slope of -1/m=5/14
So the line searched has for equation:
y+1=(x-2)*5/14
or 10x-28y+73=0
Answer:
<em>All answer below</em>
Step-by-step explanation:
<u>Equation of the Line</u>
The standard form of the equation of a line is shown below:
Ax+By=C
And the slope-intercept form is:
y = mx + b
Where m is the slope and b is the y-intercept.
If we wanted to convert from the first form to the second we will perform the following operations:
Subtract Ax:
By = -Ax + C
Divide by B:
y = -A/Bx+C/B
The coefficient of x is -A/B (fill the blank with that text) and the y-intercept is C/B (again, fill in the blank)
The slope m is the coefficient of x, m=-A/B and it can be found it you divide the opposite of A by B. The selected option is correct.
The y-intercept is the division of C by B. Again, the selected option is correct.
Answer:
Step-by-step explanation:
y=mx+b where m is the slope and b is the y intercept
m=(y2-y1)/(x2-x1), we have points (6,0) and (1,-1)
m=(-1-0)/(1-6)=1/5 so we have
y=x/5+b, using point (6,0) we can solve for b
0=6/5+b
b=-6/5
y=x/5-6/5 or more neatly
y=(x-6)/5
Area of a rectangle is given by multiplying the length and the width
Let's length be
and width be
, then the area is
