Question

A student uses the equation y = 3 - 4x to represent a linear relationship.

Answer 1

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

$y = mx + c$

• 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

$y = - 4x + 3$

• so m = -4 meaning that -4 is the gradient aka slope, and 3 is the y-intercept!
• hope this helps
