There are two straight lines.
Line 3 has a slope of - 3 and crosses the Y axis at - 10.
Line 4 goes through ( 4, - 8) and (-3, 3)) [Hint: m = (Y1 - V2)/(x1 - X2) 1
Complete the table:

Write the equation for Line 3 (y=mx+b) :
Write the equation for Line 4 (y=mx+b) :
Where do the lines cross each other? (x,y):
Line 3:
X Intercept: (10/3, 0)
Y Intercept: (0, -10)
Slope: -3
Equation: y = -3x - 10
Line 4:
X Intercept: (0, 0)
Y Intercept: (0, -8)
Slope: (-8 - 3) / (4 - (-3)) = -11 / 7
Equation: y = (-11/7)x - 8
The lines cross each other at the point (4, -8).
