Step-by-step explanation:
Q7: Given equation of line is:
Converting into slope-intercept form
Comparing with the standard slope-intercept form
We get
m = 2
As the new line has same slope as given line
Given
b = 3
The equation is given by:
Putting the values of slope and y-intercept
Q8: Given equation of line is:
converting in slope-intercept form
Dividing both sides by 3
The slope of line is: -2
The new line has same slope so,
m_1 = -2
Slope-intercept form of line is:
Putting the value of slope
Putting the point (2,1) in the equation
So the equation is:
Q9: Given equation is:
subtracting Ax from both sides
Dividing both sides by B
As the equation is in slope-intercept form, the co-efficient of x is the slope of line
So the slope is:
Hence,
