Line and point v are shown on the graph.
line is to be drawn on the graph such that it is perpendicular to line . if the coordinates of point w are (–1, y), what is the value of y?

The y-coordinate of point W is

Step-by-step explanation:

Step 1

Fin the slope of the line ST

we know that

The formula to calculate the slope between two points is equal to

we have

Substitute the values

Step 2

Find the slope of the line WV

we know that

If two lines are perpendicular, then the product of their slopes is equal to minus one

so

------->

we have

substitute the value and solve for mWV

Step 3

Find the equation of the line WV into slope-intercept form

we have

 -------> see the graph Point V is the y-intercept of the line WV

substitute

Step 4

Find the y-coordinate of the point W

Substitute the the values of x and y of point W in the linear equation

therefore

the y-coordinate of point W is

my answer is$ 12

step-by-step explanation:

because 15 -2=12
