Answer:
option Bis correct answer.
Step-by-step explanation:
given, a line passes through the point (_1,3)and has slope 2.let another point be x2 and y2.
by the slope formula,
slope (m)=
or , 2=y2_3/x2_(_1)
or, equating with slope we get,
2=y2_3
or, y2=5
again, 2=x2+1
therefore, x2=1
so the points are (1,5)........ans....

Step-by-step explanation:
The graph of g(x) is a vertically scaled version of the graph of f(x). The scale factor is 1/2, so vertical height at a given value of x is 1/2 what it is for f(x). This will make the graph appear shorter and fatter than for f(x).
The graph of g(x) is attached.
Answer:
Step-by-step explanation:
Slope of a line passing through two points and
is given by the formula,
Slope =
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '' =
= 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '' =
= ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.
