Answer:
[tex]\text{Question 1 }\Large\boxed{A.~-17}[/tex]
[tex]\text{Question 2 }\Large\boxed{A.~-10}[/tex]
Step-by-step explanation:
Question 1.
Given expression
[tex]y=-5+6x[/tex]
Given information
[tex]x=-2[/tex]
Substitute values into the expression
[tex]y=-5+6(-2)[/tex]
Simplify by multiplication
[tex]y=-5+(-12)[/tex]
Simplify by addition / subtraction
[tex]y=\Large\boxed{-17}[/tex]
Question 2.
Given expression
[tex]y+10=5x[/tex]
Requirement of the question
[tex]\text{Find the value of the y-intercept.}[/tex]
[tex]\text{The meaning of y-intercept is the point that is on the y-axis, which means x = 0 }[/tex]
Substitute values into the given expression
[tex]y+10=5(0)[/tex]
Simplify by multiplication
[tex]y+10=0[/tex]
Subtract 10 on both sides
[tex]y+10-10=0-10[/tex]
[tex]y=\Large\boxed{-10}[/tex]
Hope this helps!! :)
