Find the equation of a line that contains the points (0,0) and (6,−7). Write the equation in slope-intercept form, using fractio

shtirl [24]

Use the slope formula below:

$\large \boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }$

To form an equation of a line - we need to find a slope and the y-intercept from y = mx+b. We are given two points which we can substitute in the formula.

$\large{m = \frac{0 - ( - 7)}{0 - 6} } \\ \large{m = \frac{0 + 7}{ - 6} \longrightarrow \frac{7}{ - 6} } \\ \large \boxed{m = - \frac{7}{6} }$

We have finally got the slope. Next is to find the y-intercept. First we rewrite the equation of y = mx+b by substituting the slope.

$\large \boxed{y = mx + b}$

The equation above is the slope-intercept form. Substitute m = -7/6 in the equation.

$\large{y = - \frac{7}{6} x + b}$

Since the graph passes through (0,0) which is an origin point. In y = mx+b if the graph passes through origin point, that means the b-value is 0. Therefore:

$\large \boxed{y = - \frac{7}{6} + 0 \longrightarrow y = - \frac{7}{6} x}$

Answer

y = -7x/6
