Is (1,8) a solution to this system of equations? y = x + 7 y = 4x + 4 Choices: (A)yes (B)no

Check First Equation: First, we need to check if the point (1,8) satisfies the first equation y = x + 7. Substitute x = 1 and y = 8 into the equation to see if the equation holds true. 8 = 1 + 7 8 = 8 This is true, so the point (1,8) satisfies the first equation.Check Second Equation: Next, we need to check if the point (1,8) satisfies the second equation y = 4x + 4. Substitute x = 1 and y = 8 into the equation to see if the equation holds true. 8 = 4(1) + 4 8 = 4 + 4 8 = 8 This is true, so the point (1,8) also satisfies the second equation.

Q. Is

(1,8)

a solution to this system of equations?

\newline

y = x + 7

\newline

y = 4x + 4

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Check First Equation: First, we need to check if the point $(1,8)$ satisfies the first equation $y = x + 7$ . Substitute $x = 1$ and $y = 8$ into the equation to see if the equation holds true. $8 = 1 + 7$ $8 = 8$ This is true, so the point $(1,8)$ satisfies the first equation.
Check Second Equation: Next, we need to check if the point $(1,8)$ satisfies the second equation $y = 4x + 4$ . Substitute $x = 1$ and $y = 8$ into the equation to see if the equation holds true. $8 = 4(1) + 4$ $8 = 4 + 4$ $8 = 8$ This is true, so the point $(1,8)$ also satisfies the second equation.
