Graph the lines 2x=-y+7 and 2y=-4x+10. What is the solution?
2 answers:
Answer: Option C
C) No solution
Step-by-step explanation:
To graph both lines identify the cut points with the axes
For
The intersection with the x axis is:
The intersection with the y axis is:
Draw a line that cuts the y-axis in 7 and the x-axis in 3.5
For
The intersection with the x axis is:
The intersection with the y axis is:
Draw a line that cuts the y-axis in 5 and the x-axis in 2.5
The intersection of both lines will be the solution of the system. Observe the attached image
The lines are parallel, so they never intercept. Therefore the system has no solution

Hi there! The answer is A.
To get a proper idea of the type of function this formula represents we work out the parenthesis.
Working out the parenthesis can for instance be done using rainbow technique.
We can now see sinilarities between this function an the general function of a line in slope intercept form
The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
