y = 9/13x + 7
Step-by-step explanation:
Find the slope and then plug in a point onto the equation of the slope and solve for y-intercept
The equation of the line is:
[tex]y = \frac{9}{13}x + 7[/tex]
-----------------------
The equation of a line, in slope-intercept formula, is given by:
[tex]y = mx + b[/tex]
In which:
- m is the slope.
- b is the y-intercept.
- We are given two points, (-26,-11) and (39, 34).
- The slope is given by change in y divided by change in x, thus:
[tex]m = \frac{34 - (-11)}{39 - (-26)} = \frac{45}{65} = \frac{9}{13}[/tex]
Then:
[tex]y = \frac{9}{13}x + b[/tex]
Point (39, 34) means that when [tex]x = 39, y = 34[/tex], and this is used to find b.
[tex]y = \frac{9}{13}x + b[/tex]
[tex]34 = \frac{9}{13}(39) + b[/tex]
[tex]27 + b = 34[/tex]
[tex]b = 7[/tex]
Thus, the equation is:
[tex]y = \frac{9}{13}x + 7[/tex]
