An equilateral triangle has side lengths of 11 cm. the triangle is enlarged using a scale factor of 4. what is the length of one side of the triangle?

The first thing you should know to answer this question is that an equilateral triangle is a triangle that has the same measure for all three sides.
 We have then that using the scale factor, the new measure for each side is:
 (4) * (11) = 44cm
 
 The length of one side of the triangle is:
 44cm

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

Idon’t know what the answer is i wish i could
