the yard? (Assume two mowers are available.)
I would assume it would take 3.5 hours to mow the lawn together.
–8x + 9y = 23
B.
–8x + 9y = –23
C.
–8x + 7y = 25
D.
–9x + 8y = –23
Answer : The correct option is, (A) -8x + 9y = 23
Step-by-step explanation :
The general form for the formation of a linear equation is:
.............(1)
where,
x and y are the coordinates of x-axis and y-axis respectively.
m is slope of line.
First we have to calculate the slope of line.
Formula used :
Here,
and
Now put the value of slope in equation 1, we get the linear equation.
From the given options we conclude that the option A is an equation of the given line in standard form.
Hence, the correct option is, (A) -8x + 9y = 23
(12, 3)
(–2, –5)
(–3, 1)
(1, 15)
(5, –2)
Answer:
The points (12,3), (-2,-5) and (1,15) through which the line can pass.
Step-by-step explanation:
A line passes through the point (0, –1) and has a positive slope.
(i) The slope of the line passing through the points (0,-1) and (12,3) will be
(ii) The slope of the line passing through the points (0,-1) and (-2,-5) will be
(iii) The slope of the line passing through the points (0,-1) and (- 3,1) will be
(iv) The slope of the line passing through the points (0,-1) and (1,15) will be
(v) The slope of the line passing through the points (0,-1) and (5,-2) will be
Therefore, the points (12,3), (-2,-5) and (1,15) through which the line can pass. (Answer)
