Question

Write an equation of the line passing through each of the following pairs of points. b (5, 7), (−6, −3)

Answer 1

Answer:

y = 10/11 x + 2.45

Step-by-step explanation:

Equation of the line

First find the gradient

formula = $\frac{y2-y1}{x2-x1}$

= $\frac{-3-7}{-6-5}$

=$\frac{-10}{-11}$

= 10/11

m is the gradient

equation of a line

y- y1 = m(x-x1)

y-7 = 10/11 (x-5)

y-7 = $\frac{10}{11}x$ - $\frac{50}{11}$

y = 10/11 x + 2.45

NB i rounded of -50/11 +7  = 2.4545..... to 2.45
