The equation of a straight line is this:
y = mx + b
...where m is the slope and b is the y-intercept.
Look at the format of your equation. Are you able to see the slope and y-intercept?
y = mx + b
...where m is the slope and b is the y-intercept.

Do you get 1 b/c of the x in front of the x itself? ( imaginary 1)
The y-intercept is the plot on the graph that you get when you set y=0. Substituted into your equation, 0=x+2
Now if you solve for x, you will get the point on the line where it crosses the y-axis, or the point (x,0). Use the equation of a line: y=mx+b where m is the slope and b is the value of y at the y-intercept, to find m (the slope). (hint)The original equation is already in this form y=mx+b, so what is the coefficient of x? That will be your slope
