Mike correctly found the slope and y intercept of the line passing through the points(-5,-2)and (3,14)as follows.
y = 7x.
cost = $7 per box, so: -
y = 7x.
length of diagonal is 13.6 m
formula for length of diagonal of rectangle is given by
where l is length and w is width
for this question length (l) = 11 m and width (w) = 8 m
so length of diagonal =
the formula to find the slope of a line is m=(y2-y1)/(x2-x1). in this question: x1=3, x2=2, y1=5, and y2=1. plug in and solve:
slope-intercept form follows the format: y=mx+b, where m is the slope and b is the y-intercept. we calculated m to be 4, so the equation reads:
to solve for b, you can select one of the ordered pairs (we'll use (2, plug them in for x and y, and solve for b:
the equation is y=4x-7.
