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
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)
