Aright triangle is shown below.
229x162
the triangle is dilated by a scale factor of 2.5 to create a new triangle. what is the perimeter of the new triangle?
a
120 cm
b
24 cm
c
60 cm
d
150 c

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.

This does not make sense
