Write the equation of the line that is perpendicular to y=1/2x+3 and has a y-intercept of -4

y=-2x-4

Step-by-step explanation:

When an equation is perpendicular, then it is the equation's inverse. The inverse of 1/2 is -2

The y-intercept is b in y=mx+b. In this equation, b=-4

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
