Answer:4-x3
Step-by-step explanation:
I think that’s right
Y= x + 3
1. Find the gradient(slope)
1 - 7 / - 2 - 4
=1
2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3
Equation => Y = x + 3
Answer:
2x-y= -8
2x+y= 7
Step-by-step explanation: hopes this helps :)
4x^2 = 100
x^2 = 25
x = + or - 5
x = 5 or x = -5
Hope this helps.
Y=mx+b is what I learned and point slope is y-y1=m*x-x1
