Line y = mx + c has slope m
Line y = ( - 2 ) x + 7 has slope - 2

The slope is -2
Whenever you put a linear equation into its "standard" form, you can pick off the slope and y-intercept just by eye-balling it
"standard" form means y=mx+b
m is the slope: in your equation that's -2
7 is the y intercept. That's where the straight line cuts the y-axis. The value 7 tells me it cuts 7 units above the x-axis, specifically at (0,7)
Two additional comments: all this is true if and only if you get the y value all by itself on the left side of the equation, with +1 as the y coefficient.
The - sign in front of the slope value tells me the line leans to the left
Good luck!

Always the number before x in slope intercept form. So its -2

The equation of a straight line:
y = mx + c
where:
m is the gradient
x is a coordinate
and c is the y intercept
hence, in the equation y = -2x + 7:
m (gradient) = -2
