Answer:
f(-1) = 8
Step-by-step explanation:
f(-1) = x
f(-1) = -5(-1) + 3
f(-1) = 8
Answer:
b
Step-by-step explanation:
Answer:
y= 1/3 x +5
Step-by-step explanation:
To find the slope, we take two points
(0,5) and (15,10)
The slope is found by the formula
m = (y2-y1)/ (x2-x1)
= (10-5)/(15-0)
= 5/15
= 1/3
The slope is 1/3
The y intercept is found when x=0
When x=0 y=5
The slope intercept form of the line is
y=mx+b where m is the slope and b is the y intercept
y= 1/3 x +5
