Leah scored 13 points the first half of the basketball game, and she scored x points in the second half of the game. Write an expression to determine the number of points she scored in all. Then, find the number of points she scored in all if she scored 3 points in the second half of the game.

Expression: 13+x

Answer if she scored 3 in the second half=16

Step-by-step explanation:

Since she scored 13 points in the first half and X amount in the second, it's asking for the total number. Since X is unknown, it's simply 13+x. Then, they say X=3. Now plug 3 in for X and solve.

ie: 13+3

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
