the slope formula is y=mx+b slope-intercept form of an equation of a line. where m=slope and b=the y-intercept
At a y-intercept, the graph touches the y-axis, meaning the value of x is 0. So, in any linear equation, simply set x equal to 0 and solve for y. In the slope-intercept form of a linear equation (y = mx + b), the y-intercept value is represented by the variable b.
the formula for slope-intercept form is y=mx+b. in the equation mx is the slope and b is the y-intercept.
y=-x+5
5x - 10 = -20This equation can be restated as 5x = -10 : x = -2This is the equation of a straight line perpendicular to the x axis and passing through the point x = -2. There is no y intercept and the slope is indeterminate.
