Question

Determine the equation of a line (in standard form ax + by = c)
(-1,3) (2,-4)

Answer 1

firsty find the gradient using to points,

step 1: \[m=\frac{ y2-y1 }{ x2-x1 }\]

then:
step2:
\[y-y1 = m(x-x1) \]

step3: make y the subject. your straight line equation is done.
\[y = ...\]

Answer 2

sorry i forgot for step 2:
you could use (x1,y1) = (-1,3) or (2,-4)

Answer 3

In step 3, express the equation in the form: Ax + By = C to put it in the standard form.
