Answer:
7 3/5
Step-by-step explanation:

Plug it into point-slope form.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
So plug in -1 for x1, 2 for y1, and 0.9 for 'm':
y - 2 = 0.9(x + 1)
Simplify to get in slope-intercept form:
Distribute 0.9 into the parenthesis:
y - 2 = 0.9x + 0.9
Add 2 to both sides:
y = 0.9x + 2.9
Answer:
2
Step-by-step explanation:
2u+10=22+u
or,2u-u=22-10
or, u=2____1
The slope formula is y2-y1/x2-x1 so if you plug in the numbers you get 3/5. the slope is 3/5

The tax is 11.76
168+ 11.76 is 179.76
