Answer:
At Point A, y = 1
At Point B, y = 1/4
At Point C, y = -2
At Point D, x = -3 2/3
Explanation:
Given that the equatuon is y = (-3/4)x + 1/4. In the table, you have to find the value of y. In order to find y, you have to substitute x value into the equation :
Point A,
Let x = -1,
y = (-3/4)(-1) + 1/4
= 3/4 + 1/4
= 4/4
= 1
Point B,
Let x = 0,
y = (-3/4)(0) + 1/4
= 1/4
Point C,
Let x = 3,
y = (-3/4)(3) + 1/4
= -9/4 + 1/4
= -8/4
= -2
For Point D, it is slightly different. It have given us the y value so we can just substitute y value into the equation to find x value :
Let y = 3
3 = (-3/4)(x) + 1/4
-3x/4 = 3 - 1/4
= 11/4
-3x = 11/4 × 4
= 11
x = 11 ÷ -3
= -11/3
