Answer:
-3
Step-by-step explanation:
La intercepcion con y se produce cuando x= 0, por lo que si reemplazamos x por 0, queda que y= -3
-x+5=x^2
x^2+x-5+0
x=-1+-sqrt (1+20)/2
x= -1+-sqrt (21)/2
x=-1+- 4.6/2
x=-1+4.6/2
x=3.6/2
x=1.8
x=-1-4.8/2
x=-5.8/2
x=-2.9
Answer:
y=(3/2)x + 1
Step-by-step explanation:
use formula y=mx+b
M is slope
B is y intercept
use point (2,4) for Y2 and X2, and point (0,1) for Y1 and X2 to find the slope.
(Y2(4) - Y1(1))/ (X2(2) - X1(0)) =
(4-1)/(2-0)= 3/2 for slope=M
y intercept is just the point found on the y axis (0,1) so it's just 1. B=1
so then plug in the numbers for the variables.
y=(3/2)x + 1
