Answer:
y-intercept: (0,6)
slope = -2
equation: y = -2x + 6
Step-by-step explanation:
1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.
2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula 
and solve:
So, the slope is -2.
3) With the found information, use the slope-intercept formula 
to write the line's equation. Substitute values for the 
and 
.
represents the slope, so substitute -2 in its place. represents the y-intercept, so substitute 6 in its place. This gives the following equation:

Alright! Well Zoe = 6 when Lulu = 12. Zoe is 10 so lulu is now 20.
Answer:
x = -4
Step-by-step explanation:
If y is equal to-x + 2 then you can plug that into the second equation as x - 4(-x + 2) = -28 after this distribute out the -4 to get x + 4x - 8 = -28. After this combine the like terms to get 5x = -20. Then get x by itself by dividing by 5 to get x = -4.
Do the equation 1200=500+11.50x
700=11.50x
Then divide 11.50 both sides
