For the linear equation that contains the points (-1,-4) and (6,10), we have that:
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
In this problem, it has points (-1,-4) and (6,10), hence, considering the slope is given by change in y divided by change in x, we have that:
[tex]m = \frac{10 - (-4)}{6 - (-1)} = 2[/tex]
Then:
[tex]y = 2x + b[/tex]
Point (6,10) means that when x = 6, y = 10, and this is used to find b.
[tex]y = 2x + b[/tex]
[tex]10 = 2(6) + b[/tex]
[tex]b = -2[/tex]
The function is:
[tex]y = 2x - 2[/tex]
The y-intercept is y = -2.
For the x-intercept, we have that:
[tex]2x - 2 = 0[/tex]
[tex]x = 1[/tex]
The x-intercept is x = 1.
