Question

Tell Esther the ordered pair is a solution of y=-4x+5 a) (1,2) b) (0,-4)

Answer 1

the expression is,

y = -4x + 5

poitn a is

a(1,2)

put x = 1

y = -4(1) + 5

y = -4 + 5

y = 1

so it is not the satisfying the equation thus, this pair is not the solution

point b is

b(0,-4)

put x = 0

y = -4(0) + 5

y = 5

so it is not the satisfying the equation thus, this pair is not the solution

both the points are not the solution of the given equation
