Katherine's cell phone bill is $45 monthly plus $0.50 per international text that she makes. Write an equation in slope-intercept form where x
represents the number of international texts and y represents Katherine's
total cost of her phone bill and international texts.

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

Find the value of x for which the lines are parallel.
