Plans for a stadium are drawn on a coordinate grid. one wall lies on the line y=2x+3. a perpendicular wall passes through the point (4,-7). write the equation of the line that contains the new wall. a. y= (-1/2)x-5 b. y=2x-15 c. y=(1/2)x-9 d. y= -2x+1

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

answer: 5

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
