Question

Write an equation of the line that passes through points (3, 7) and (5, 11).

Answer 1

y = mx + b

where
m = slope
b = y-intercept

you can find the slope using these two points
(x, y)
(3, 7)
(5, 11)

To find the slope use the formula:
\[ m = \frac{y_2- y_1}{x_2 - x_1}\]

Then after you solve for m, sub m into the equation
y = mx + b
then insert one of your points into the equation and solve for b

Answer 2

okay thank you :) but I don't think the possible answers are in y=mx+b format :/

Answer 3

All lines have the standard formula
y = mx + b

so follow my method and you will come to the right answer

Answer 4

okay, thank you for your help :)
