2(3x+2)=2x-1+x solve
alina1380 [7]
First multiply and dstribute
a(b+c)=ab+ac
2(3x+2)=6x+4

If a line with a slope of -2 crosses the y-axis at (0,3) what is the equation of the line
Ghella [55]
Hello!

The equation can be written as seen below. You only need a y-intercept and slope to write the equation.

y=-2x+3                             (it intercepts at a y-value of 3).

I hope this helps!
