Question

If the point (2,0) lines on the graph of the equation 5y=ax+10 find the value of a.

Answer 1

Answer:

-5

Step-by-step explanation:

the common eqn for points on a graph is ax+by=c

over here if the eqn is rearranged, it will be ax-5y = -10

therefore, 5y = 2a+10

here x=2 and y=0 (substitute these values in the given qn

ax+10=5y

2a+10=5y

2a+10=0

2a = -10

a = -5
