Y=Mx+b is slop intercept form the slope of the line is 1/4 and b is the y intercept which the line crosses over at -3 so it would be Y=1/4x-3
To graph this equation, I am going to change it up so you can understand. a, in this case, is x and 38 would be y(but it is already solved). Therefore the equation is y = 8x - 10. This follows the format y = mx +b.
To graph: Since your x is 6, your y is missing, but since it's already solved it's 38. Your coordinates would (6, 38).
The answer is in a pattern the pattern consist that 12 is what each number equals
1.1n represents the total cost of n packages of pencils.
2.2m represents the total cost of m pads of paper
The entire expression represents the total cost of Yolanda's school supplies.
For the first one it’s x=6.6
And the second one is x=-11
