How to find a point of intersection with two equations

Asked by admin @ 29/10/2021 in Mathematics viewed by 353 People

when finding the intersection of two lines from both algebra I and geometry you first set the linear equations equal to each other. find the intersection point of the two lines whose equations are shown below. y= 5x+1 and 2x-11

Answered by admin @ 29/10/2021

Y = 5x + 1
y = 2x - 11

Substituting the first equation in to the second
5x + 1 = 2x - 11
3x = -12
x = -4

Plugging x = -4 into either equation

y = 2(-4) - 11
y = -8 - 11
y = -19

The point where the two lines intersect is (-4, -19)
