Question

Write the equation of the line that passes through (2, 4) and (1, –3) in slope-intercept form.
Answer

y = 7x + 18

y = 7x + 10

y = 7x – 18

y = 7x – 10

Answer 1

slope

m = (y2-y1)/(x2-x1)



m = ( -3- 4)/(1-2)



m = (-7)/(-1)



m = 7

--------------

equation:

y = mx+b


4 = (7)(2)+b


4 = 14+b


4-14 = b


-10 = b


b = -10


So the equation of the line is y = 7x-10


which is choice D
