Lets look at it as the Pythagorean theorem, so A²+B²=C²
First step: find the X (a) and the Y (b)
|6-0| = 6
|-4-2|= 6
Second step: 6²+6²=c²
36+36=C²
72=C²
√72=√C²
8.49=C
your final answer would be 8.49 units
Answer:
Area is 24
Explanation: times the length by the breath (width)
Solving the given equation for y results in y = (-4/7) x + (a constant).
The new line has a slope that is the negative reciprocal of -4/7. That slope is +7/4.
The new line passes thru (-4, -7). Thus,
the equation for this new line is y - (-7) = (7/4)(x - [-7]), or
y + 7 = (7/4)(x+7)
Let's put this into slope-intercept form:
y = -7 + (7/4)x + (49/4), or y = (7/4)x + (49/4) - 7, or
y = (7/4)x + 21/4 (answer in slope-intercept form)
