Or
The slope intercept form is
Step-by-step explanation:
Assuming you want to graph the straight line given in point-slope form as
Then we need at least two points on this line
When we compare to the point-slope formula then we obtain (-5,-2) as a point on this line so we plot it.
When x=0, y=4(0+5)-2=18 so we plot (0,18)
We then draw a straight line through as shown in the attachment.
On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:
