The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, using the points (0, 0) and (3, 12):
y - 0 = [(12 - 0)/(3 - 0)](x - 0)
y = 4x

Answer:
Option a is the correct answer.
Step-by-step explanation:
Let x,y and z represent the marks scored in first,second and third tests respectively.
Total score is 239, then:
x+y+z = 239 -------1
Combined scores of first and second tests is 59 more than that of third test,then:
x+y = 59+z
x+y-z = 59 ---------2
The score of second test is 25 more than that of third test, then:
y = 25+z
0x+y-z = 25 --------3
The matrix equation for this situation is:
