Base and height of triangle whose height is four more than seven times its base. Whats the base and height? Thanks :) ...?
Alex787 [66]
Assuming B is for Base and H is for Height of the triangle. The statement "Height is four more than seven times its base" indicates to us that the base is the variable. 
So we'll have B = x, then we can arrive at the value of H which is 7x + 4.

(0,1)(4,2) find the slope and y-intercept using the point slope formula
MariettaO [177]

Hello, Jssoyg! I've solved the problem for you below. I hope it helps.

Slope equation is\frac{y2 - y1}{x2 - x1}. The two points are (0,1) and (4,2), so the equation becomes \frac{2 - 1}{4 - 0} = \frac{1}{4}. We now know that the slope is 1/4, so now let's write it in the y = mx + b format. Plug in the m, x, and y values:2 = 4*\frac{1}{4} + b.

This becomes 2 = 1 + b which means b = 1.

Your answer is y = 1/4x + 1. Hope this was helpful. :D
