Answer:
vertex: (4,-6), y= -14
Step-by-step explanation:
vertex can be derived from this formula
(4, -6)
to find y intercept you need to set x=0
y=2(0-4)-6
=-8-6
y= -14
B. four times the value of y = the value of y+9
The line would intersect with the y-axis at (0,0)
A would be 1 as b would be -4
Area = base x height
= 14 * 9
= 126 inches squared.
Area of triangle
= 126 / 2
= 63
Answer = 63
