From the picture you can see that (0, -5) is a point on the function and that (2, -4) is another point. Using these you can find the slope of the function with the equation

$(y_{2} -y_{1})/(x_{2}-x_{1} )$

We can substitute in the points so it looks like

$(-4--5)/(2-0)$ or $1/2$ which is the slope of the function

Now, since the y-intercept is (0, -5) on the graph, the b part in the slope-intercept form of the equation would be -5, leaving us with the equation y=1/2x-5

Solve using substitution or elimination. y = x + 1 2x - 5y = 4

andrew-mc [135]

Substitute y = x + 1 into 2x - 5y = 4

-3x - 5 = 4

Solve for x in -3x - 5 = 4

x = -3

Substitute x = -3 into y = x + 1

y = -2

Therefore,

x = -3

y = -2
