Write the equation of the line that passes through the point (-1,7) and is perpendicular to the line x=4. explain how you determined this equation.

The answer is: y = 7

Step-by-step explanation:

For x = 4, it is a vertical line where everything is x = 4. No matter what y is, x always equals 4.

For the line y = 7, it is a horizontal line, perpendicular to the line x = 4. The line y = 7 passes through the point (-1, 7) and all other similar points where y = 7.

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
