The value of x is 5

<em><u>Solution: </u></em>

<em><u> The slope of a line is given by formula: </u></em>

Slope = \frac{ y_2-y_1}{x_2-x_1}

From given,

slope = \frac{11}4}\\\\(x_1, y_1) = (x, -7)\\\\(x_2, y_2) = (-1, 4)

<em><u>Substituting the values we ge</u></em><em><u>t,</u></em>

\frac{11}{4} = \frac{4+7}{-1-x}\\\\-11 - 11x = 11 \times 4\\\\-11-11x = 44\\\\11x = -11-44\\\\11x = 55\\\\x = 5

Thus the value of x is 5
