Yup it's correct :) good job!
Answer:
The values are
m = 13
b = 17
Step-by-step explanation:
1239 = 94m + b ------eqn 1
810 = 61m + b -----------eqn 2
Let's take eqn 1, let's make b the subject of the formula
1239 - 94m = b
Since b = 1239 - 94m
Insert the value of b into the eqn 2
810 = 61m + (1239 - 94m)
810 = 61m + 1239 - 94m
Collect like terms
810 = 61m - 94m + 1239
810 = - 33m + 1239
810 - 1239 = - 33m
- 429 = - 33m
The minus sign cancels each other
Making m the subject
m = 429 / 33
m = 13
Since we've gotten the value for m, insert the value of m= 13 into the eqn 1
1239 = 94m + b
m = 13
1239 = 94 (13) + b
1239 = 1222 + b
1239 - 1222 = b
17 = b
b = 17
m = 13
b = 17
The vertical shifts in graphs are caused by a constant added to the output (y - axis).
<h3>What is vertical shift in a graph?</h3>
Vertical shifts are outside changes that affect the output (y- axis) values and shift the function up or down (vertical direction).
Horizontal shifts are inside changes that affect the input (x-) axis values and shift the function left or right
<h3>The cause of vertical shift in a graph</h3>
The vertical shift results from a constant added to the output (y - axis). The graph will move up if the constant added is positive OR it will move down if the constant is negative.
Thus, the vertical shifts in graphs are caused by a constant added to the output (y - axis).
