Question

Choose the equation that represents a line that passes through points (-1, 2) and (3, 1).

0 4x - y = -6
O x + 4y = 7
Ox - 4y = -9
O 4x + y = 2

Answer 1

The answer is x + 4y = 7

Equation of a line is y = mx + c

Where m is the slope

c is the y intercept

Slope of the line between the points

(-1, 2) and (3, 1) is

Slope = 1-2/ 3+1 = - 1/4

Equation of the line using point

(-1, 2) is

y - 2 = -1/4(x + 1)

4y - 8 = - x - 1

x + 4y = 7

Hope this helps you
