Answer:
y = -4x + 8
Step-by-step explanation:
The equation of a line is written in slope-intercept form : y = mx+b
m is the slope
We are given two points, so let's find the slope of the line first:
Slope = ΔY/ΔX = 4 - (-4) / 1 - 3 = 8 / -2 = -4
The slope is -4
So far, our equation is y = -4x + b
We can input a point's x and y value to find b, the y-intercept
Let's use point (1, 4)
4 = -4(1) + b
4 = -4 + b
b = 4 + 4
b = 8
The equation is y = -4x + 8

Triangles are similar and only differ in size meaning they are dilated
So first we have to find the scale factor of dilation (by how much the smaller triangle got bigger)
Find scale factor:
2.4a=4.8
z=2
Find x:
we multiply the original side of the small side with the scale factor of 2
2.8(2)=x
5.6=x
So, x=5.6
