Answer:
14
Step-by-step explanation:
hi! so the question is asking what h is when you input -18 for x, right?
inputing in this question means to substitute, meaning that in this equation, -18 will take the place of x!
- let's see what the equation looks like now
- easy as that!
now let's do the math :)
- because of PEMDAS, remember to do the fraction (dividing) first!
we can change that to --> h = 17 - 3
h = 14
let me know if you're still confused!
Answer:
y = 6x - 2
Step-by-step explanation:
slope intercept form is y = mx + b
m = slope
b = y-intercept
They give us the slope (m) which is 6 and the y-intercept (b) which is -2. PLug it into the equation
y = mx + b
y = 6x - 2
