Find an equation in slope-intercept form of the line that has slope 9 and passes through point A(-9, -1).

y = 9x+80

Step-by-step explanation:

We can use the slope intercept form of a line

y = mx+b where m is the slope and b is the y intercept

y = 9x+b

Substitute the point in for x and y

-1 = 9(-9) +b

-1 = -81 +b

Add 81 to each side

-1+81 = b

80 =b

The equation is y = 9x+80

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
