Question

Find the equation of the line in standard form that passes through the following points. Eliminate any fractions and simplify your answer.


(2,-10) and (7,-9)

Answer 1

gradient = y2-y1/x2-x1

-9--10/7-2

gradient = 1/5 or 0.2

y = 1/5 x + c

(subsitute a coordinate)

-10 = 0.2 (2) + c

-10 = 0.4 + c

c = -10.4 or-52/5

y = 0.2x - 10.4

$standard \: form \\ (2 \times {10}^{ - 1} )x - (1.05 \times {10}^{1} )$
