To find the equation of a line knowing two points it passes through, we must first find the slope and then substitute the x and y values to figure out the y intercept.
First thing is to find the slope using the formula m = Δy ÷ Δx
m = 5 - (-2) ÷ 4 - (-5)
Now we simplify
m = 7 ÷ 9
Our equation so far is y = 7/9x + b. Now we can substitute the values of x and y from a point to figure out the answer. The equation here uses the point (4,5)
5 = 7/9 · 4 + b
Get b on one side
5 - 28/9 = b
Simplify
b = 1 + 8/9
That makes the equation of the line y = 7/9x + (1 + 8/9)

Step-by-step explanation:
Answer:
The area of the triangle is 10 square units.
Step-by-step explanation:
The formula for area of a triangle is A =
bh.
The problem gives us this information:
b = 4 units
h = 5 units
You can use the formula and plug the numbers into the equation to find your answer of 10 square units.
