Question

15. The straight line graph of the linear equation Y = a +bX,
slope is horizontal if:
O a) b = 0
O b) b #0
O c) b = 1
O d) a = b​

Answer 1

Answer:

b=1

its your required answer ❤️

Answer 2

Answer:

The slope is horizontal if b=0

Explanation:

A line is horizontal when the value of y for both points is the same.

Slope formula = $\frac{y_2-y_1}{x_2-x_1}$  

Since $y_2 = y_1$ slope is 0

In a line equation y = mx+c

m represents the slope.

In the given equation m=b =0.
