Question

What is the value of b if the graph of 2x+by=10 is to have a y-intercept of (0,5)?


The value of b is ______________________________

Answer 1

Answer:

2 (?)

Step-by-step explanation:

substitute 0 and 5 into the eqution so it becomes 2x0 + bx5 = 10

2x0 = 0

to get b by itself 10/5 = 2

Answer 2

(0,5) mean x = 0 and y = 5
So , we will put in equation
2(0)+b(5)=10
0+5b =10
b = 10/5 =2
