What is the slope of this line?

y = 3x + 4

Step-by-step explanation:

The line passes through points (-3, -5) and (0, 4)

The slope of the line = change in y-axis ÷ change in x-axis

i.e the slope = = = 3

Taking another point (x, y) on the line,

The slope = = 3

Simplifying the equation above gives;

y - 4 = 3x

y = 3x + 4 (equation of the line)

step-by-step explanation:

32.50-7.50=25

225/25=11

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
