jim_thompson5910 · Answer

first find the slope of the line through those two points

jim_thompson5910 · Answer

Use the slope formula


m = (y2-y1)/(x2-x1)


m = (-1-3)/(3-4)


m = (-4)/(-1)


m = 4

jim_thompson5910 · Answer

now find the y-intercept

y = mx + b

y = 4x + b

3 = 4(4) + b

solve for b
