Question

Is this point (20, 13) on this line? Explain your reasoning.

Answer 1

Answer:

Yes

Step-by-step explanation:

Point (20,13) fits on the line y=1/2x+3

You can prove this by plugging in the x and y values.

13=1/2(20) +3

1/2(20)=10

13=10+3

13=13

Therefore (20,13) fits on the line

Answer 2

Answer:

Yes, point (20,13) is on the line, the same slope and y-intercept.

Step-by-step explanation:

y-intercept of the line = 3

Slope of the line = 1/2

Point (20, 13)

y-intercept of (point (20,13) with slope 1/2 =

13 - (1/2)(20) = 13 - 10 = 3

y-intercept= 3
