Answer:
y = -3x - 2
Step-by-step explanation:
Equation of a line passing through and slope m is,
Slope of a line passing through and
is,
Slope =
Slope of the line passing through (0, -2) and (1, -5) will be,
Slope =
m = - 3
Therefore, equation of the line passing through (0, -2) and slope = -3 will be,
y + 2 = -3(x - 0)
y + 2 = -3x
y = -3x - 2
In the given figure we have two similar triangles:
a) Triangle ABC
b) Triangle ADE
Two sides of triangle ABC are 2 and x
The two corresponding sides of triangle ADE are (2+1)=3 and 1
The ratio of corresponding sides of similar triangles is always equal, so we can write:
Therefore, the measure of x will be 2/3
