Write the equation in slope-intercept form in each line based on the information give
1 answer:
Answer:
y= 6x -8
Step-by-step explanation:
<u>Slope-intercept form: </u>
y= mx +c, where m is the gradient and c is the y-intercept.
Gradient
= 6
y= 6x +c
To find the value of c, substitute the equation with a pair of coordinates.
When x= 1, y= -2,
-2= 6(1) +c
c= -2 -6 <em>(</em><em>-6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
c= -8
Thus, the equation of the line is y= 6x -8.

The line is vertical, so the slope is infinite
Step-by-step explanation:
Given two points with coordinates and
, the slope of the line passing through the two points is given by the equation
In this problem, the coordinates of the two points are:
and
which means:
Substituting all these values into the equation of m, we find the slope of the line:
The slope is infinite: this is because the line is vertical.
