Answer:
Step-by-step explanation:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and b is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named as the "slope-intercept form".The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y.
The slope m of this line shows its steepness, or slant - It can be calculated like this:
                          m = change in y-value  /change in x-value
The equation of any straight line, called a linear equation, can be written as: y = mx + b ....
 
        
             
        
        
        
The slope is 7. whatever number is next to x is the slope. if there is no x then it is a horizontal or vertical line.
        
                    
             
        
        
        
Y= -2+4
If X equals -2, you want to plug -2 in for X.
I hope I helped!
