Question

Find the equation of the line with the slope undefined and the x-intercept (-4,0)

Answer #1

Since the given line has a x-intercept, its slope cannot be 0, for otherwise, it would be parallel to the X-Axis.

The equation of a line with slope m ( m ≠ 0) and x-intercept c is y = mx +c. Since this line passes through the point (-4,0), hence on substituting x = -4 and y = 0 in its equation, we get m*(-4) + c = 0 or, c = 4m.

Thus, the equation of a line with the slope undefined and the x-intercept (-4,0) is y = mx +4m, where m (m ≠ 0) is its undefined slope.

The equation of a line is given below.

Find the slope and the y-intercept.
Then use them to graph the line.
how do you solve this question by using run/rise formula and
graph it?
slope: 2/5
y-intercept: -1

Consider the line with non-zero slope m and y-intercept b,
that is the line described by the equation y = mx + b where m is
not equal to 0. Use dot products of vectors to show that any line
perpendicular to this one must have a slope of -1/m. Also show that
in the case where m=0, any perpendicular line must be vertical (and
hence have undefined slope).
