Graph each equationon a grid. -2x+5y=15
put this solution on YOUR website!
The equation is already in standard form, so we will just use the solver to illustrate it.
Standard form is ax+by=c
I hope this helps!
DESCRIBE a linear EQUATION: slope, intercepts, etc
describes a sloping line. For any
equation ax+by+c = 0, slope is
X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 15/-2 = -7.5.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 15/5 = 3.
Slope is --2/5 = 0.4.
Equation in slope-intercept form: y=0.4*x+3.
