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
