A student uses the equation y = 3 - 4x to represent a linear relationship.
1 answer:
Step-by-step explanation:
- The student is viewing the equation in the wrong way, he needs to put the equation in standard from / correctly first in order to be able to find the slope.
- The straight line formula is
- looking at the formula in that form m=gradient (slope) , and c is the Y intercept.
- so putting the above equation in the correct form
- so m = -4 meaning that -4 is the gradient aka slope, and 3 is the y-intercept!
- hope this helps

Option C: is the coordinates of C after translation.
Explanation:
The triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3).
Also, given that the triangle is translated 4 units down and 3 units left.
We need to determine the coordinates of the vertex C after translation.
The triangle is shifted 4 units down means subtracting 4 units from the y - coordinate of the graph.
Thus, it can be written as
Also, the triangle is shifted 3 units left means subtracting 3 units from the x - coordinate of the graph.
Thus, it can be written as
Thus, the translation is given by
The vertices of C after translation can be determined by
Thus, is the coordinates of C after translation.
Hence, Option C is the correct answer.
