Answer

The two equations intercept at point (-6,23)

Work Step by Step

To find the point of intersection between the two equations, we have to equal them to each other. y = -3x + 5 y = -4x - 1 Since, y = y and both of the equations are equal to y, we can substitute the values in place of y. -3x +5 = -4x - 1 + 4x + 4x x +5 = - 1 - 5 - 5 x = -6 Now we can substitute the x value into either of the two equations to find the y-value y = -4(-6) - 1 y = 24 - 1 y = 23 From this we get the ordered pair (-6,23) and this is where the two points intercept
