Pls help!! What is the equation for the line in slope-intercept form

y = -4x + 9

Step-by-step explanation:

using any two points, in this case (0, 5) and (3, -7) you can find slope by using this formula:

plug in the x- and y- values of the two points above

y = -4x + b

use any point of the line and plug it into the equation above

5 = -4(0) + b

5 = -4 + b

5 + 4 = -4 + b +4

9 = b

the equation in full is y = -4x +9

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
