Hint: We know that the standard equation of straight line where m is the slope of the line and c is the y-intercept of the straight line. So if we have the value of slope and y-intercept then we can write the equation
Complete step by step answer:
The given slope in the question is -4 and the value of y-intercept is 6
We know that the equation of straight line y = slope x + y-intercept
So we can figure out the equation of straight line
Now let’s draw the graph and point out the y-intercept
We can see in the above figure the straight line is and the y-intercept is point A(0,6)
The equation of the straight line with slope -4 and y-intercept 6 is
Note:
We can find the equation of the straight line by another method, we know that the y-intercept is 6 so the straight pass through the point (0,6) and the slope of a line is -4. Let the point (x,y) lie on the straight line so the value of slope will be which is equal to -4.
So we can write
Multiplying x in LHS and RHS we get
Now adding 6 in both LHS and RHS we get
We can see the above equation is the equation of the straight line that is
