Answer:
second option is correct (for question no 20)
Step-by-step explanation:
coordinate points are:
(3,1) = (x1,y1)
(5,9) = (x2,y2)
slope (m) = y2-y1/x2-x1
=9-1/5-3
=8/2
=4
Now using slope intercept form
y=mx + b
y=4x + b
since the line passes through the point (3,1) it satisfies the equation
y=4x + b
1=4*3 + b
1-12 = b
-11 = b
substituting the value of b in equation
y=4x + b
y=4x +(-11)
y=4x - 11
Answer:
B
Step-by-step explanation:
One way to tell is to put both equations into slope-intercept form. That form is usually written where m is the slope and b is the y-intercept.
Solve the first equation for y.
The slope of this line is -3, and its y-intercept is 5/2.
Solve the second equation for y.
The slope of this line is -3 and its y-intercept is 2.
The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.
