Step 1.1.1
Apply the distributive property.
y=7x−3x−3⋅−1
Step 1.1.2
Multiply −3 by −1.
y=7x−3x+3
y=7x−3x+3
Step 1.2
Subtract 3x from 7x.
y=4x+3
y=4x+3
Step 2
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.
