16: 10(-9) +4 = -90 +4 = -86
17. 7^2 - 7 = 49-7 = 42
18. -9^2 - -9 = 81+9 = 90
19. 10(5) +4 = 54, 3*54 = 162
20. 3*5 = 15, 10(15) +4 = 154
The answer would be 40/63 as simplified.
Hope this helps! Can i have brainiest?

Answer:


Step-by-step explanation:
The y-intercept is where x is equal to 0, and the x-intercept is where y is equal to 0, so:

The equation is written in slope-intercept form:

m is the slope and b is the y-intercept, so the y-intercept is -18.
Now set the value of y to 0 to find the intercept of x:

Solve for x. Add 18 to both sides:

Divide both sides by 8:

The x -intercept is
