Answer:
10. [tex]y=\frac{3}{5}x+7.2[/tex]
11A. [tex]m=-\frac{3}{5}[/tex]
11B. [tex]m=\frac{5}{3}[/tex]
Step-by-step explanation:
10. Let's first write the slope-intercept form down and fill in the information we got (which is not much).
[tex]y=mx+b\\y=\frac{3}{5}x+b[/tex]
Now we just need to find the b; the y intercept.
To do that, we plug in the point given (-2,6).
[tex]6=\frac{3}{5}(-2)+b\\6=-\frac{6}{5}+b\\6+\frac{6}{5}=b\\b=7.2[/tex]
[tex]y=\frac{3}{5}x+7.2[/tex]
------------------------------------------------------
A parallel line always has the same slope as its pair
11A. [tex]m=-\frac{3}{5}[/tex]
A perpendicular line has it's slope same as it's pair, but it is multiplied by [tex]-1[/tex] and the numerator and denominator are switched around.
11B. [tex]m=\frac{5}{3}[/tex]
