Answer:
Step-by-step explanation:
- Firstly, plug in the point and slope into the slope-intercept equation format:
When lines are parallel to one another, their slopes are the same. But they have different y-intercepts. To explain further, slope is the angle of measure of a line from a horizontal standpoint and knowing that parallel angles must have the same angle, it can be concluded that parallel lines would have the same slope or in other words, an equal slope.
Now solving, use algebraic concepts:
11 = -8(-1) +b (Now solve for b)
11 = 8 + b (Subtract 8 from both sides) (Use the "Right" to "Left")
-8 -8
3 = b (Switch terms)
b = 3
Now let's write the equation with only slope and y-intercept.
Getting the result of:
y = -8x + 3

Answer:
g(x)= 5x
Step-by-step explanation:
You should go back to the graph and notice that the abscissa 1 goes with the ordinate 5.
Now ask yourself how do I get 5 using 1. There many ways but notice that the function is growing and both functions f and g geow the same way. Wich mean that g(x)= 5x is a valid option.
notice that 0 is going with o at the ordinate.
some little calculations . m=(5-0)/(1-0)= 5
so the function is g(x)=5x+p
p is 0 since it is the first ordinate
so g(x)= 5x
