Question 1

Y = 2x + 4; x = -2.5 find the value of of y for the given value of x

Question 2

$\:\:\:\:\:\:\star\small \underline{ \boxed{ \sf{ y = 2x +4 }}}\\$

$\:\:\:\:\:\:\longrightarrow \sf {y = 2* -2.5 +4}\\$

$\:\:\:\:\:\: \sf {\because x = -2.5}\\$

$\:\:\:\:\:\:\longrightarrow \sf {y = 2* \bigg((-25)/(10)\bigg) +4}\\$

$\:\:\:\:\:\:\longrightarrow \sf {y = (-50)/(10)+4}\\$

$\:\:\:\:\:\:\longrightarrow \sf {y = \frac{-5\cancel{0}}{1\cancel{0}}+4}\\$

$\:\:\:\:\:\:\longrightarrow \sf {y = -5+4}\\$

$\:\:\:\:\:\:\longrightarrow \boxed{ \tt{ \pmb{ \red{y = -1}}}}\\$

$\\ \therefore \underline{ \cal{ \pmb{\underline{\:y \: \frak{\purple{= -1 \: }}. }}}}\\$
