That kind of depends on what kind of curve this is. If it is a line then
m=(-5-1)/(-4+6)=-6/2=-3
y=-3x+b
1=-3*-6+b
b=19
y=-3x+19
(y-19)/-3=x
x intercept is 19/3
if this is not a line we need to know what it is.

Use the factor slope formula: y – y1 = m(x – x1) you could plug in the two (-22.8, -34.2) or (40 4.2, -25.2) for x1 and y1 y -34.2 = -3(x – 25.2) y – 34.2 = -3x + 25.2 y = -3x + 109.8 as a result interior the type y = mx + b; b =109.8 that’s the y intercept.
