Y = mx + b
slope(m) = -2/3
(-4,1)...x = -4 and y = 1
now we sub and find b, the y int
1 = -2/3(-4) + b
1 = 8/3 + b
1 - 8/3 = b
3/3 - 8/3 = b
-5/3 = b
so ur equation is : y = -2/3x + (-5/3) which can be written as : y = -2/3x - 5/3
If two angles are known to be the same, the triangles are similar! If this is true, then by default the third angle will be the same. So, triangles that have two of the same angles MUST be similar!

Answer: f(x) = 3x - 1
Step-by-step explanation:
y - 5 = 3(x - 2); now solve for y;
y = 3(x - 2) + 5; now distribute the 3 and add like terms;
y = 3x - 6 + 5
y = 3x -1 ; replace y with f(x);
f(x) = 3x - 1
