So the two equations are

1) Y = x^2 + 1

2) Y = mx – 4

Equate both the equations

x^2+1 = mx -4

x^2 +5 + mx = 0

My teacher told me that from here use the quadratic formula in questions similar to these but in those questions the slope was given and the y-intercept wasn’t. so it worked out.. How do I find the value of m in the equations…
