Answer:
y = 2x + 8
Explanation:
the equation of a line in slope-intercept form is.
y = mx+b
where m is the slope and b the y-intercept
to calculate m use the gradient formula
m = (y2−y1 ) / (x2−x1)
let (x1,y1)=(-6,-4) and (x2,y2)=(-4,0)
m = (0 - (-4)) / (-4 - (-6) = 2
y = 2x+b←is the partial equation
to find b substitute either of the 2 given points
into the partial equation
using (-6, -4) then
-4 = -12+b⇒b=8
y = 2x + 8←is the equation of line
