Question

Write an equation in slope-intercept form of the line through point P(6, –1) with slope 4.
A. y + 1 = 4(x – 6)
B. y + 6 = 4(x – 1)
C. y = 4x – 25
D. y = 4x – 1

Answer 1

first of all
\[slope=\frac{\Delta y}{\Delta x}\] \[slope = \frac{y - y_{1}}{x-x_{1}}\]
inserting the value of the slop and the point (x1,y1) will give \[y = 4x-25\] which is option C
