Question 595354: Write in slope-intercept form the equation of the line with the given slope and y-intercept.
m=2,b=-1

You can put this solution on YOUR website! Hi, there--
.
The slope-intercept form of a linear equation has the form,y = mx + b, where m is the slope and b is the y-intercept. If you graphed the equation on a coordinate plane, it would be a straight line with a slope of m. The line would intercept the y-axis at the point (0,b).
.
In your problem, you just need to substitute the values for m and b that you were given in the problem. (Be careful about that pesky negative intercept, though.) Here's how it works:
y = mx + b
y = 2x + (-1)
y = 2x - 1
.
If you graph this equation, you will see that the line has a slope of 2, and it crosses the y-axis at the point (0,-1).
.
I hope this helps! Free free to email me if you still have questions.
