Can someone please help with this maths !!!!!

Answer:
C) -3
Step-by-step explanation:
Rearrange your equation so that it is in slope-intercept form (y = mx + b). The m in the equation is the gradient.
y = 7 - 3x
y = -3x + 7
The m-value is -3. This means that the gradient is -3.
Answer:
c)
Step-by-step explanation:
Slope intercept form of a line: y = mx + b
m---> slope or gradient
b ----> y-intercept
y = -3x + 7
Gradient = -3
