What is the equation in point slope form of the line that passes through the point (–1, –3)(–1, –3) and has a slope of 4?
a y−1=4(x−3)y−1=4(x−3)
b y+3=4(x+1)y+3=4(x+1)
c y+1=4(x+3)y+1=4(x+3)
d y−3=4(x−1)

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
