Which line has a slope of 1 2?
y = ½m + c. The slope 1/2 means that if you start at any point on the line and go to the right two and up one, you will hit the line again. That means the there are an infinite number of parallel lines that can have 1/2 as their slope.
How do you find the y-intercept with the slope and a point?
Using the “slope-intercept” form of the line’s equation (y = mx + b), you solve for b (which is the y-intercept you’re looking for). Substitute the known slope for m, and substitute the known point’s coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.
What is the y-intercept of a slope?
In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.
What is the equation of the line passing through the point 1/2 and has a slope of 5?
The equation in point-slope form of the line passing through (1, 2) and (2, 5) is y = 3x – 1.
What does it mean if a slope is 1 2?
Slope = 12 means 2 y units for each 1 x unit.
How do you find y-intercept in an equation?
The y-intercept formula says that the y-intercept of a function y = f(x) is obtained by substituting x = 0 in it. Using this, the y-intercept of a graph is the point on the graph whose x-coordinate is 0. i.e., just look for the point where the graph intersects the y-axis and it is the y-intercept.
How do you find the y-intercept?
When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable. To find y-intercept: set x = 0 and solve for y. The point will be (0, y). To find x-intercept: set y = 0 and solve for x.
How do you find y-intercept?
The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
What’s the y-intercept formula?
What is the Y intercept of a line that has a slope of 3 and passes through point (- 1 )?
Recall that MX in the equation is the slope, which is 3, and b, the y intercept, is 1. Overall making the equation Y= 3x + 1 or Y= 3/1 + 1. I hope this helped!
What is the equation of a line that has a slope of 1 and passes through 3 4 )?
Binayaka C. The equation of the line is y=3x+1 .
