Answer:
Step-by-step explanation:
recall the two formulas
y = mx - b slope-intercept
y - y1 = m(x-x1) point-slope
with these we can get the equation . we also need to find the slope m
m = y2-y1 / x2-x1
m = 3 - (-1) / 2-4
m = 3 + 1 / -2
m = 4 / -2
m = -2
now with the slope known, plug in either point into the point-slope formula and work to the slope-intercept formula, I'll use (2,3) as the point to plug in.
y - 3 = -2(x-2)
y - 3 = -2x +4
y = -2x + 7
there.. that's your answer
y = -2x + 7
