the equation is 3x+y=11

The slope of the line through points (x1,y1) and (x2,y2) is given by : \(\huge m=\frac{y_1-y_2}{x_1-x_2}\) now,just put the values and find m.

so x1=-3 y1=5 x2=1 and y2=7 now just plug in the values and simplify :)

ogg so 1/2?
hartnn

What is the equation of a line that has a slope of -5 and passes through the point (0, 2)?
hartnn
  • hartnn
the equation of line in slope point form is y-y1 = m (x-x1) m= slope = -5 here (x1,y1) = point = (0,2) here now just put values.
