Question

At what point does y = 2x + 3 intercept: a) The y-axis: b) The x-axis:​

Answer 1

Answer:

Step-by-step explanation:

a) Interception at y-axis :

- Take x-value as 0

=> y = 2(0) + 3

=> y = 3

=> y-intercept is (0, 3)

b) Interception at x-axis :

- Take y-value as 0

=> 0 = 2x + 3

=> 2x = -3

=> x = -3/2

=> x-intercept is (-3/2, 0)

Answer 2

Answer:

a)(0, 3)

b)(-3/2, 0)

Step-by-step explanation:

a) y-axis : x=0

so instead of x you write 0 : y = 2 * 0 + 3

and you get y = 3

b) x-axis : y=0

so instead of y you write 0 : 0 = 2 * x + 3

2 * x = -3

x = -3/2
