Answer:
As below
Step-by-step explanation:
using eq from problem 4) y = -45x + 1080
then use the point slope formula with the slope of the above line at -45 and plug in your given point of (8, 240)
y-y1 = m(x-x1) where m is the slope above
y-240 = -45 (x - 8 ) this is an equation for the line but the teacher probably wants the slope intercept form... the formula is y = mx + b
soooo...
y-240 = -45x + 360
y = -45x +360 + 280
y = -45x + 640
there you go :)

Answer:
Step-by-step explanation:
Solve the y
y -3 = 1/2(x + 2)
y = 1/2(x + 2) + 3 Add
Pick points that you wish to substitute for x values.
x = 0 x = 2 x = 4
y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3
y = 1/2(0 + 2) + 3 y = 1/2(2 + 2) + 3 y = 1/2(4 + 2) + 3
y = 1/2(2) + 3 y = 1/2(4) + 3 y = 1/2(6) + 3
y = 1 + 3 y = 2 + 3 y = 3 + 3
y = 4 y = 5 y = 6
Locate the following point on graph (x, y); (0, 4), (2, 5), (4, 6)
