Question

math help please

Solve the following system of equations graphically.

y - 4 = 0
2x - y - 2 = 0

What is the solution set?

Answer 1

a. {(-3, -4)}
b. {(-3, 4)}
c. {(3, 4)}

Answer 2

i think its b. but im not sure

Answer 3

to solve graphically plot the points, draw the lines and find the intersection

Answer 4

for each line you need 2 points
the easiest to use are the value of y when x =0 and the value of x when y = 0

Answer 5

line 1 y - 4 = 0 so y = 4
line 2 2x - y - 2 = 0 when x = 0 0 - y -2= 0 so y = -2 and when y = 0 2x - 0 -2 =0 so 2x = 2 therefore x = 1
for line 2 the points are (0, -2) and (1, 0 )

Answer 6

can you sketch the graph and find the intersection?
