Answer:
- 4
Step-by-step explanation:
Let the function is y = ax + b ..... (1)
Now, the points (-4,-2) and (-2,-10) lie on the straight line, so the points will satisfy the equation (1).
Hence, - 2 = - 4a + b ........ (2) and
- 10 = - 2a + b ......(3)
Now, solving equations (2) and (3) we will get the values of a and b.
Hence, - 2a = 8, ⇒ a = -4
Again from equation (3), we get b = - 10 + 2a = - 10 + 2(-4) = - 18
Therefore, the linear equation is y = - 4x - 18
Hence, the slope of the straight line is - 4. (Answer)
