What rule would you allow to test weather (x,y) is on line l
n200080 [17]

Answer:

Step-by-step explanation:

If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.

Slope of a line passing through two points C(4, 5) and D(8, 10),

m = \frac{y_2-y_1}{x_2-x_1}

m = \frac{10-5}{8-4}

m = \frac{5}{4}

Equation of the line passing through C(4, 5) and slope m = \frac{5}{4}

y - y' = m(x - x')

y - 5 = \frac{5}{4}(x-4)

y = \frac{5}{4}x-5+5

y = \frac{5}{4}x

If point B(4, 0) lies on the line CD,

0 = \frac{5}{4}(4)

0 = 5

Which is not true.

Therefore, point B doesn't lie on line CD.

Mario made a table with the rules below
Lady_Fox [76]
  • It will be option A.
  • x - coordinate is 1. If we multiply 3 with 1, it will be 3. And if we multiply 3 with 3, it will be 9.
  • y- coordinate is 1. If we add 3 with 1, it will be 4. And adding 3 with 4, we get 7.

<u>Answer:</u>

<u>a- (1,1) (3,4) (9,7)</u>

Hope you could get an idea from here.
