[8] The y-intercept is the point at which the line crosses the y-axis. EXPERT TIP Grace Imson, MA Math Instructor, City College of San Francisco
WebTo find where y=1/2x+5 and the original line y=-2x intersect, set them equal to each other. Let y in both of the equations equal the same value. You are doing this because at the two lines' point of intersection, both lines will share the same x and y value. So, let y=1/2x+5 equal y=-2x. That means -2x = 1/2x+5 0= 5/2x +5 -5 = 5/2x -2 =x WebThe straight line through two points will have an equation in the form \(y = mx + c\). We can find the value of \(m\) , the gradient of the line, by forming a right-angled triangle using the ...
WebPoint-slope Form of an Equation of a Line. The point-slope form of an equation of a line with slope m and containing the point (x1, y1) is: y − y1 = m(x − x1) We can use the point-slope form of an equation to find an equation of a line when we know the slope and at least one point. Then, we will rewrite the equation in slope-intercept form. WebThe equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx + b becomes y = 0x + b y = b. Also,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.
