Doing last-minute work...yeah

Assuming the line equation is y=mx+b

Input (-3,10) -3m+b=10 (1)

Input (4,20) 4m+b=20 (2)

Equation 2-Equation 1: 7m=10, m=10/7

Input m into Equation 1: -3*10/7+b=10

b=10+30/7=100/7

Therefore the equation is y=10/7 x+100/7

When y=0, 10/7 x+100/7=0,x=-10

So the x intercept is (-10,0)

When x=0, y=100/7

So the y intercept is (0,100/7)
