Question

Find the point of intersection for the pair of linear equations.
x +y = 0.3
y=3x + 16.7

Answer 1

B

Explanation:

You should find the solution for this system of equations (The value of x is the first coordinate for the point of intersection, the value of y is the second coordinate for the point of intersection)

X+y=0.3

y=3x+16.7

use 3x+16.7 instead of y in the first equation(do it to get only x in the first equation)

x+3x+16.7=0.3

4x+16.4=0

4x=-16.4

x=-4.1

y=0.3+4.1=4.4

B
