What value of x gives y=-2?

plz help !

-1

Step-by-step explanation:

to find x, use the following formula:

y = mx + b

(y = 0)

(m = change in y-value ... which is 2)

(x = change in x-value ... which is 2)

(b = y-axis ... which is -2)

y = mx + b

y = + -2

= 1

y = 1 + -2

y = -1

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
