F(1)=6(1)+2
= 6+2
=8
g(f(1))= 2x/5 +4/5
= 2(8)/5 +4/5
= 16/5 +4/5
= 20/5

Y = x - 9 meets the y-axis at (0,-9)
y = -2x - 3 meets the y-axis at (0,-3)
This is because for every linear equation, there is a formula corresponding to it as y=mx + c, where (0,c) is where it meets the y-axis. As we assign the value of 0 to x, only c will be left to equal y, being the intercept.
Answer:
A point on the line would be (-3, -7) and the slope if -3/2
Step-by-step explanation:
We can find a point on the line by choosing any value for x and putting it in to the equation. Then we can find the y value. For the purpose of this problem, we will use x = -3.
y + 1 = -3/2(x + 7)
y + 1 = -3/2(-3 + 7)
y + 1 = -3/2(4)
y + 1 = -6
y = -7
And we can find the slope simply by looking for the number outside of the parenthesis on the right side of the equal sign (-3/2)
