Answer:
y=x+1
m=1
b=1
Step-by-step explanation:
-2x+2y=2
+2x +2x
2y=2+2x
divide by 2
y=1+x
rewrite
y=x+1
Since b is the y intercept, b would equal 1.
The slope of the line, or m, would be 1 as well.
Answer:
last option: y = (-2/3)x + 5
Step-by-step explanation:
slope-intercept equation: y = mx + b
where m is the slope and b is the y-intercept
if slope m = -2/3, then y = (-2/3)x + b
if point (3, 3) is on the line, substitute x=3 and y=3 into the equation and solve for b:
3 = (-2/3)3 + b
⇒ 3 = -2 + b
⇒ b = 5
Therefore, equation: y = (-2/3)x + 5
Answer: f(4) = 5
Step-by-step explanation:
If the point (4, 5) is on the graph of a function, this means that when you input 4 you get an output of 5.
Inputs are usually shown with the x-coordinate, and outputs are usually shown with the y-coordinate.
This means that (4, 5) is an input of 4 for an output of 5.
