Question 1186979

Find the equation of the line having slope  −2  and  x -intercept of  5 .

You may enter your equation in either the slope-intercept or point-slope form.  Make sure to enclose fractions in parentheses, for example: y = (9/2)*x+(5/2).
<pre>Point-slope form: {{{matrix(1,3, y - y[1], "=", m(x - x[1]))}}}, where: {{{matrix(3,3, m, "=", slope, x[1], "=", x-coordinate, y[1], "=", y-coordinate)}}}. 
In this case, x-intercept results in the point (5, 0) 
{{{matrix(1,3, y - y[1], "=", m(x - x[1]))}}} then becomes: {{{matrix(1,3, y - 0, "=", - 2(x - 5))}}} ------ Substituting {{{matrix(3,3, - 2, for, m, 0, for, y[1], 5, for, x[1])}}}
Equation of the line: {{{highlight_green(matrix(1,3, y, "=", - 2x + 10))}}}
