Answer:
The point-slope form looks like this:
y - y1 = m (x - x1) where (x1,y1) is a point on the line and m is the slope
Therefore for the first question:
m = 7
(x1,y1) = (-4,6)
Ans: y - 6 = 7 (x + 4) [Note: x - (-4) = x + 4]
For the second question:
The slope-intercept form looks like this:
y = mx + b
Since you have the point-slope form, all you have to do is solve for the slope-intercept form:
y - 6 = 7 (x + 4) [First, Isolate the left side so you only have y left]
y = 7(x+ 4) + 6 [Then solve for the right side until you have mx + b]
y = 7x + 28 + 6
y = 7x + 34
Ans: y = 7x + 34
