value of x=2 is-8 and y=-4 is -1024
Answer:
Answer D: Slope: 4 y-intercept: -10
Step-by-step explanation:
The answer is D because in the slope-intercept equation(y=mx+b) m=slope and b=y-intercept. This equation is not in the correct order but the slope is 4 because it is where the m would be and it's next to the x. The y-intercept is -10 because it's where the b would be in this equation, it's by itself, and you can see the y separate from any numbers.
Hope this makes sense and helps!!!!
Answer: 2 is the y intercept
Step-by-step explanation:
Slope is rise over run and in this problem our y intercept is 2 because it is defined as the y. Negate your 9 and put it over the y intercept to make into a fraction to represent slope. This makes it y = mx + b form now.
y = - 9/2x + 2
