Answer:
y = -2x + 6 and y = 1/3x - 7
Step-by-step explanation:
For A, using rise over run, you can count 2 units up and 1 unit left of any given point to get to the next point. Because left is the negative direction on a graph, the 1 unit is negative. To calculate slope, divide the rise (2) over the run (-1) and substitute the slope as m into y = mx + b. In the formula, b is the y-intercept (where the line crosses the x axis). The y-intercept of A is 6, so replace b in the formula with 6:
y = -2x + 6
The slope of B is 1/3 and the y intercept is -7, so substitute those values into the formula again to get the answer for B:
y = 1/3x - 7
Answer:
-5x-12
Step-by-step explanation:
Given f(x) = -5x+3, to get f(x+3), we are going to replace x in f(x) with x+3 as shown;
f(x) = -5x+3
f(x+3) = -5(x+3)+3
f(x+3) = -5x-15+3
f(x+3) = -5x-12
Hence the function f(x+3) is -5x-12
