What is the slope of y=-1+3xy=−1+3x

Answer 1

y=-1 +3xy

1 =-1 +3x

3x = 2

x = 2/3 has undefined slope. It's a vertical line

y = -1 +3x has slope = 3 = the coefficient of the x term when the equation is solved for y

y=1

x = 2/3

(2/3, 1) is the solution, the intersection point of the graph of the 2 lines' equations

y=-1 +3xy

1 =-1 +3(2/3)(1) = -1 +2 =1

y =-1 +3x

1= -1 +3(2/3) = -1+2 = -1
