- Plug x = 0 into the equation and solve for y.
- Plot the point (0,y) on the y-axis.
- Plug y = 0 into the equation and solve for x.
- Plot the point (x,0) on the x-axis.
- Draw a straight line between the two points.
What is the slope of y =- 2x 1?

What is the y-intercept y =- 2x?
Using the slope-intercept form, the y-intercept is 0 .
How do you find the y-intercept of Y 1 2x?
- Consider standard form y=mx+c.
- Where c is the y-intercept.
- In your equation c still exists in that its value is 0.
- So y=mx+c→y=12x+0.
- So the y-intercept is at y=0.
What is the formula to find the Y?
Review the slope-intercept form. You can describe a straight line with the formula y = mx + b, where m is the slope and b is the y-intercept. Now that we know the slope m and a point (x,y), we can use this equation to solve for b, the y-intercept.
What is the Y intercept in a table?
The point where the equation crosses the y-axis is the Y-Intercept. When finding the Y-Intercept from a Table, you have to discover the y-value from the table when the x-value is equivalent to zero.
Where would the line y =- 2x 1 lie?
It is a straight line curve passing through 3rd, 4th and 1st quadrant.11 Aug 2015
